Acoustic cloaking device hides objects from sound

Summary:

Engineers have demonstrated the world's first three-dimensional acoustic cloak. The new device reroutes sound waves to create the impression that the cloak and anything beneath it are not there. The phenomenon works in all three dimensions, no matter which direction the sound is coming from or where the observer is located, and holds potential for future applications such as sonar avoidance and architectural acoustics.

Bogdan Popa, a graduate student in electrical and computer engineering,
shows off the 3D acoustic cloak he helped design and build as a member of Steven Cummer’s laboratory.



Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated the world's first three-dimensional acoustic cloak. The new device reroutes sound waves to create the impression that both the cloak and anything beneath it are not there.

The acoustic cloaking device works in all three dimensions, no matter which direction the sound is coming from or where the observer is located, and holds potential for future applications such as sonar avoidance and architectural acoustics.

The study appears online in Nature Materials.

"The particular trick we're performing is hiding an object from sound waves," said Steven Cummer, professor of electrical and computer engineering at Duke University. "By placing this cloak around an object, the sound waves behave like there is nothing more than a flat surface in their path."

To achieve this new trick, Cummer and his colleagues turned to the developing field of metamaterials -- the combination of natural materials in repeating patterns to achieve unnatural properties. In the case of the new acoustic cloak, the materials manipulating the behavior of sound waves are simply plastic and air. Once constructed, the device looks like several plastic plates with a repeating pattern of holes poked through them stacked on top of one another to form a sort of pyramid.

To give the illusion that it isn't there, the cloak must alter the waves' trajectory to match what they would look like had they had reflected off a flat surface. Because the sound is not reaching the surface beneath, it is traveling a shorter distance and its speed must be slowed to compensate.

"The structure that we built might look really simple," said Cummer. "But I promise you that it's a lot more difficult and interesting than it looks. We put a lot of energy into calculating how sound waves would interact with it. We didn't come up with this overnight."

To test the cloaking device, researchers covered a small sphere with the cloak and "pinged" it with short bursts of sound from various angles. Using a microphone, they mapped how the waves responded and produced videos of them traveling through the air.

Cummer and his team then compared the videos to those created with both an unobstructed flat surface and an uncloaked sphere blocking the way. The results clearly show that the cloaking device makes it appear as though the sound waves reflected off an empty surface.

Although the experiment is a simple demonstration showing that the technology is possible and concealing an evil super-genius' underwater lair is a long ways away, Cummer believes that the technique has several potential commercial applications.

"We conducted our tests in the air, but sound waves behave similarly underwater, so one obvious potential use is sonar avoidance," said Cummer. "But there's also the design of auditoriums or concert halls -- any space where you need to control the acoustics. If you had to put a beam somewhere for structural reasons that was going to mess up the sound, perhaps you could fix the acoustics by cloaking it."

Russian inventor patents invisibility technique

A professor from the department of quantum and optical electronics of the Ulyanovsk State University in western Russia has patented a method of making things invisible, Interfax news agency reported. The so-called invisibility cloak, created by Oleg Gadomsky, is called “The method of conversion of optical radiation” in the patent. Gadomsky had been long experimenting on nanoparticles of gold. He now claims to have invented a sub-micron stratum of microscopical colloid golden particles that makes an object placed behind it invisible to an observer. “Only static objects can be made invisible for the time being, as during motion the radiation frequency changes. But soon it will be possible to create a cap of darkness and a magic cloak like Harry Potter’s,” the scientist believes.

Russian Inventor Patents New Optical Camouflage Technique

by
Kristopher Kubicki

The technology for atomic level invisibility might be closer than you'd think

MosNews and NewsRU are reporting that Russian professor Oleg Gadomsky has patented a new method of optical camouflage.  The professor, versed in both quantum and optical electronics, uses gold nanoparticles arranged in a stratum that cloaks the image of an object to the other side of the stratum.  The patent, unfortunately, does not show a scale demonstration of this technology or even if the technology works yet.

Gadomsky's technology is completely different than existing methods of optical camouflage that exist today.  In 2003, the TACHI laboratory of the University of Tokyo demonstrated an "invisibility cloak" -- which was actually no more than a projection of the image behind the cloak projected back onto the cloak.  Gadomsky plans to actually disrupt the radiation in such a manner to "bend" light around the stealthed object behind the nanoparticle wall.

Nanostructured antireflective optical coating

[ PDF ]

Inventor: GADOMSKY OLEG NIKOLAEVICH [RU]

Abstract

An antireflective coating applied onto a substrate in the form of at least one layer of nanoparticles arranged on the aforementioned substrate at equal distances from each other in accordance with a specific nanostructure. The nanoparticles are made from a material that under effect of incident light generates between the neighboring particles optical resonance interaction with a frequency that belongs to a visible optical range. The interaction between the nanoparticles reduces reflection of the incident light. The nanoparticles have a radius in the range of 10 to 100 nm and a pitch between the adjacent particles that ranges between 1.5 diameters to several diameters.

BACKGROUND OF THE INVENTION

[0002] An antireflective coating may be defined as a coating that has a very low coefficient of reflection. The antireflection coating reduces unwanted reflections from surfaces and is commonly used on spectacles and photographic lenses.

[0003] Whenever a ray of light moves from one medium to another (e.g., when light enters a sheet of glass after traveling through air), some portion of the light is reflected from the surface (known as the interface) between the two media. The strength of the reflection depends on the refractive indices of the two media as well as the incidence angle. The exact value can be calculated using the Fresnel equations.

[0004] When the light meets the interface at normal incidence (i.e. perpendicularly to the surface), the intensity of the separated light is characterized by the reflection coefficient or reflectance, R:

[0000] [mathematical formula - see original document]

[0000] where n0 and nS are the refractive indices of the first and second media, respectively. The value of R varies from 0.0 (no reflection) to 1.0 (all light reflected) and is usually quoted as a percentage. Complementary to R is the transmission coefficient or transmittance, T. If the effects of absorption and scatter are neglected, then the value T is always 1-R. Thus if a beam of light with intensity I is incident on the surface, a beam of intensity RI is reflected, and a beam with intensity TI is transmitted into the medium.

[0005] For a typical situation with visible light traveling from air (n0 1.0) into common glass (nS 1.5), the value of R is 0.04, or 4%. Thus only 96% of the light (T=1-R=0.96) actually enters the glass, and the rest is reflected from the surface. The amount of light reflected is known as the reflection loss. Light also may bounce from one surface to another multiple times, being partially reflected and partially transmitted each time it does so. In all, the combined reflection coefficient is given by 2R/(1+R). For glass in air, this is about 7.7%.

[0006] In the case of a single-layer coating of the glass, the light ray reflects twice, once from the surface between air and the layer, and once from the layer-to-glass interface.

[0007] From the equation above with refractive indices being known, reflectivities for both interfaces can be calculated, and denoted R01 and R1S, respectively. The transmission at each interface is therefore T01=1-R01 and T1S=1-R1S. The total transmittance into the glass is thus T1ST01. Calculating this value for various values of n1, it can be found that at one particular value of optimum refractive index of the layer, the transmittance of both interfaces is equal, and this corresponds to the maximum total transmittance into the glass.

[0008] This optimum value is given by the geometric mean of the two surrounding indices, i.e.:

[0000]
n1=[square root of]{square root over (n0nS)}.

[0009] For the example of glass (nS 1.5) in air (n0 1.0), this optimum refractive index is n1 1.225. The reflection loss of each interface is approximately 1.0% (with a combined loss of 2.0%), and an overall transmission T1ST01 is approximately 98%. Therefore an intermediate coating between the air and glass can reduce the reflection loss by half of its normal (uncoated) value.

[0010] Practical antireflection coatings, however, rely on an intermediate layer not only for its direct reduction of reflection coefficient, but also on use of the interference effect of a thin layer. Assume that the layer thickness is controlled precisely such that it is exactly one-quarter of the wavelength of the light deep ([lambda]/4), forming a quarter-wave coating. If this is the case, the incident beam I, when reflected from the second interface, will travel exactly half its own wavelength further than the beam reflected from the first surface. If the intensities of the two beams, R1 and R2, are exactly equal, then since they are exactly out of phase, they will destructively interfere and cancel each other. Therefore, there is n0 reflection from the surface, and all the energy of the beam must be in the transmitted ray, T.

[0011] Real coatings do not reach perfect performance, though they are capable of reducing a surface's reflection coefficient to less than 0.1%. Practical details include correct calculation of the layer thickness; since the wavelength of the light is reduced inside a medium, this thickness will be [lambda]0/4n1, where [lambda]0 is the vacuum wavelength. Also, the layer will be the ideal thickness for only one distinct wavelength of light. Other difficulties include finding suitable materials, since few useful substances have the required refractive index (n 1.23) that will make both reflected rays exactly equal in intensity. Magnesium fluoride (MgF2) is often used, since this is hard-wearing and can be easily applied to substrates using physical vapor deposition, even though its index is higher than desirable (n=1.38).

[0012] Further reduction is possible by using multiple coating layers, designed such that reflections from the surfaces undergo maximum destructive interference. One way to do this is to add a second quarter-wave-thick higher-index layer between the low-index layer and the substrate. The reflection from all three interfaces produces destructive interference and antireflection. Other techniques use varying thicknesses of the coatings. By using two or more layers, each of a material chosen to give the best possible match of the desired refractive index and dispersion, broadband antireflection coatings that cover the visible range (400-700 nm) with maximum reflectivities of less than 0.5% are commonly achievable.

[0013] The exact nature of the coating determines the appearance of the coated optics; common anti-reflective coatings on eyeglasses and photographic lenses often look somewhat bluish (since they reflect slightly more blue light than other visible wavelengths), though green-and-pink-tinged coatings are also used.

[0014] If the coated optic is used at non-normal incidence (i.e. with light rays not perpendicular to the surface), the antireflection capabilities are degraded somewhat. This occurs because a beam travelling through the layer at an angle "sees" a greater apparent thickness of the layer. There is a counter-intuitive effect at work here. Although the optical path taken by light is indeed longer, interference coatings work on the principle of "difference in optical path length" or "phase thickness". This is because light tends to be coherent over the very small (tens to hundreds of nm) thickness of the coating. The net effect of this is that the anti-reflection band of the coating tends to move to shorter wavelengths as the optic is tilted. Coatings can also be designed to work at a particular angle; beam splitter coatings are usually optimized for 45[deg.] angles. Non-normal incidence angles also usually cause the reflection to be polarization dependent.

[0015] Known in the art are methods of imparting antireflective properties to optical devices by coating them with single-layered or multilayered interferential coatings.

[0016] Application of N sequential layers provides 2N parameters (i.e., N refractive indices and N thicknesses). Such a coating makes it possible to efficiently suppress reflection in a predetermined angular range by selecting predetermined combinations of reflective indices and thicknesses. Thus, at high angles of incidence for N wavelengths the coefficient of reflection from the coating can be reduced to [a value close to] zero. By arranging the minimums of reflection over the spectrum, it becomes possible to obtain a coating with a predetermined integral reflective capacity. In order to obtain an antireflective coating with efficient achromatization, it is necessary to have a wide assortment of substances that differ in dispersions and indices of refraction. Therefore, an essential problem associated with improvement of interferential coatings is broadening of the assortment of transparent substances suitable for application onto substrates in the form of homogeneous films [M. Born, E. Wolf. Principles of Optics, Pergamon Press, 1968, Chapter 1; and Ph. Baumester, et al. Optical Interference Coatings, Scientific American 223 (6), 58 (1970)].

[0017] Thus, known methods of forming antireflective coatings possess the following disadvantages.

[0018] 1) They cannot provide the minimal reflective capacity in a wide range of wavelengths of visible light spectrum, i.e., from 400 nm to 800 nm, and in a wide range of angles of incidence 0 to 90[deg.].

[0019] 2) The known processes are limited in the choice of substances for application of alternating layers. These substances must be transparent in the visible part of the optical spectrum; films made from these substances must be homogeneous and possess appropriate mechanical properties and high adhesive capacity.

[0020] 3) Widening of an antireflection spectrum requires an increase in the number of layers, and this leads to accelerated aging of interferential coatings.

[0021] 4) The known interferential antireflective coatings do not provide minimal reflection in a wide range of wavelengths and incidence angles when such coatings are applied onto surfaces of opaque media.

[0022] 5) A common disadvantage of conventional interferential coating is that their structure, properties, and design must always be considered with reference to the nature, properties, and characteristics of the substrate onto which the coating is applied.

[0023] Recent development of nanotechnology opened a new avenue for improving properties of the coatings based on the use of new physical phenomena inherent only to nanostructures.

[0024] Nanometer-scaled layers and structures are becoming more and more important in optics and photonics. Very thin layers are routinely used as anti-reflective coatings for displays, lenses and other optical elements. High-grade anti-reflective coatings can be created using nanoporous polymer films. Ultrathin layers are being increasingly utilized in solar cells and are a key element in the realization of large and brilliant displays based on organic light-emitting diodes (OLEDs) merged with nanoparticle coatings. Tiny nanoclusters make possible not only silicon-based light emission which can be used in optocouplers but also novel sensor devices and integrated optical systems.

[0025] Patterning of nanoparticles for controlling optical properties of coatings is known. For example, US Patent Application Publication No. 20050118411 (inventor C. Horne) published in 2005 describes nanoscale particles, particle coatings/particle arrays and corresponding consolidated materials based on an ability to vary the composition involving a wide range of metal and/or metalloid elements and corresponding compositions. In particular, metalloid oxides and metal-metalloid compositions are described in the form of improved nanoscale particles and coatings formed from the nanoscale particles. Compositions comprising rare earth metals and dopants/additives with rare earth metals are described. Complex compositions with a range of host compositions and dopants/additives can be formed using the approaches described herein. The particle coating can take the form of particle arrays that range from collections of disbursable primary particles to fused networks of primary particles forming channels that reflect the nanoscale of the primary particles. Suitable materials for optical applications are described along with some optical devices of interest.

[0026] This new technique is based on the fact that when nanoparticles of certain metals or dielectrics are introduced into coating layers, the nanoparticles change or improve properties. In the field of optical coatings, the technique based on the use of nanoparticles is used as a new approach for obtaining antireflective coatings that impart new properties to optical elements, e.g., optical filters. The introduction of the aforementioned new technique makes it possible to improve quality and reduce the number of coating layers.

[0027] Other methods of arranging nanoparticles into nanostructures are described, e.g., in European Patent Application Publication EP 1510861A1 published Feb. 03, 2003 (Inventors: O. Harnack, Et al.); US Patent Application Publication 2006/0228491A1 published 10o.12.2006, (inventors M. Choi, et al.), etc.

[0028] However, the inventor herein is not aware of any published material teaching that interaction between patterned and closely arranged nanoparticles may be used for reducing reflection in an optical coating.

OBJECTS AND SUMMARY OF THE INVENTION

[0029] It is an object of the invention to provide antireflective optical coatings with minimal possible reflective capacity in the entire range of visible wavelengths of 400 nm to 800 nm. It is another object to provide an antireflective coating that effectively works irrespective of the direction of light that is incident in an arbitrary direction in the limits of a hemisphere, i.e., in the range +-90[deg.] from the perpendicular to the surface of the aforementioned reflective coating. It is a further object to provide an antireflective coating capable of providing a coefficient of reflection close to zero based on the use of nanoparticles of metals or dielectrics arranged in a specific pattern in the material of a coating.

[0030] The invention relates to an optical coating with light-reflective capacity reduced practically to zero due to interaction of specially patterned nanoparticles. The invention is based on the effect found by the inventor and consists of suppressing reflective capacity of an optical system due to interaction between nanoparticles arranged at very short distances from each other in the form of specific patterns. Such a system has several parameters that can be used for changing reflective capacity of the system from 0 to 1, thus converting the system from an ideal mirror to an absolutely transparent body in a wide range of the optical spectrum. The effect results from conversion of frequency of optical radiation due to interaction between neighboring nanoparticles. The invention can be used for applying antireflective coatings onto optical lenses, filters, etc. The coatings are composed of substantially identical nanoparticles of a predetermined material with a radius in the range of 10 to 100 nm, which are arranged with a predetermined structure on the surface of a body. Such coatings can reduce reflective capacity of a transparent optical medium, e.g., of quartz glass, practically to zero in the wavelength range of 400 nm to 800 nm. Antireflective coatings of the invention in the form of a monolayer of nanoparticles are noticeably superior to conventional multilayered interferential wide-band reflective coatings. The coatings may also be used for application onto non-transparent bodies of different shapes and configuration for reducing reflection from the surfaces of such bodies...

DETAILED DESCRIPTION OF THE INVENTION

[0050] The nanoparticles form a predetermined structure that maintains the aforementioned anti-reflective effect provided by the nanoparticle interaction. Types of such nanostructures are determined by specific requirements of coating. Examples of the nanostructures are described below.

[0051] The nanostructured system may be located on the surface of a body 32 which is an object of reflective capacity decrease, or may be located inside of the body 32.

[0052] In order to reduce optical reflection from transparent or non-transparent bodies, it is required that absorption in the nanostructure be minimal. Reflection from the surface of the coating 30 also should be minimal, while the transmission of light through this surface should be maximal. As has been mentioned above, the effect of decrease in reflective capacity is achieved due to interaction between the nanoparticles and depends on the structure of the nanoparticle system.

[0053] The nature of interaction between identical (or different) nanoparticles is described below.

[0054] When the body 32 coated with the coating 30 is irradiated with an external light L, the impurity atoms or valence electrons contained in the system are subject to quantum transitions that generate in isolated nanoparticles optical resonance with certain frequency [omega]0 that belongs to a visible optical range. When distances R between the centers of nanoparticles are comparable in size with radii a of the nanoparticles, this leads to the formation of optical near-field resonances in the field of natural light. Frequencies w of these resonances to a great extent depend on distances R and on the radii a of the nanoparticles. Mathematical substantiation of the effect of the near-field resonance is disclosed by O. N. Gadomsky in "JETP, vol. 97, No. 3, pp. 466-478 (2003); by O. N. Gadomsky, in Journal "Physics-Uspekhi", 43(1), 1071-1102 (2000); and O. N. Gadomsky, et al. "Optics and Spectroscopy", Vol. 98, No. 2, (2005). Frequencies of secondary radiation depend on the concentration of impurity atoms for dielectric nanoparticles and on the concentration of valence electrons for metallic nanoparticles.

[0055] Dissipation of light from a pair of silver nanoparticles on a glass substrate was experimentally realized as described by N. Tamaru, et al. in Applied Physics Letters, 80, No. 10, 1826 (2002) (Resonant light scattering from individual Ag nanoparticles and particle pairs). This situation can also be easily explained on the basis of optical neaqr-field resonances.

[0056] The physical meaning of the reflection minimization effect in a nanostructured system with reference to interaction between nanoparticles can be conveniently demonstrated with an example of a semi-infinite nanocrystal composed of pairs of nanoparticles. Such a situation was considered in the work of O. N. Gadomsky, et al., with an example of interaction between glass nanospheres with sodium atoms as the impurity. (See O. N. Gadomsky, et al., Metastructural systems of activated nanospheres and optical near-polar resonances [Optics and Spectroscopy, 98, 300 (2005)]). Subsequent numerical calculations showed that the aforementioned optical effect of antireflection can also be obtained in a pair of gold nanoparticles...

[0060] The coating of the present invention is based on the above-described effect of antireflective action. This effect can be realized on superthin nanocrystals composed of one or several monolayers. The aforementioned nanocrystals are in principle different from photonic and globular crystals in which dimensions of the globules are comparable with the wavelength of the external optical radiation. In nanocrystals, dimensions of nanoparticles are considerably smaller than the wavelength of light. However, these particles are not points. As seen in FIGS. 2a, 2b, dependence from radii of particles is significant. A review of photonic and globular crystals is presented by I. S. Fogel et al. in "Pure Appl. Opt.", 7, 393, 1998.

[0061] The effect revealed by the inventor in a system of interacting nanoparticles indicates that for a given material of nanoparticles the reflective and light-transmissive capacity of the optical system are effected mostly by the following three main parameters: a radius of nanoparticles, a distance between the neighboring nanoparticles, and a structural factor.

[0062] The physical antireflective effect described above may be used in practice, e.g., for applying antireflective coatings of the invention onto surfaces of optical lenses, filters, or other optical elements made from transparent materials, e.g., glass. It should be noted in this connection that when a light beam passes through interfaces, e.g., between glass and air, then, depending on the type of glass, reflection of light from the interface reduces the power of the light beam at least by 4 to 9%. If the light falls onto the surface at an angle, the loss of light power is even higher. Since, as a rule, modern optical devices and instruments contain a significant number of interfaces between light-refractive elements, reflection of light from multiple interfaces may in some cases lead to losses of light power as high as 80% or more. Such significant losses not only affect light power but, even worse, also generate a diffuse background that produces a significant masking action after several reflections of light that passes through the system. Use of the antireflective coating of the invention makes it possible to alleviate the above problem by reducing reflective capacity of a multiple-interface optical system...

Application Example of the Antireflective Nanostructured Coating

[0077] It is understood that practical realization of the above-described monolayered nanostructure composed of identical nanoparticles arranged in a regular lattice is not a trivial task. One of the methods that can be employed for the preparation of such structure is advanced electron-beam lithography (E-Beam lithography) with an electron beam diameter of about several nanometers (see . . . ). In general, the procedure performed by means of E-Beam lithography consists of sequential exposure to an electron beam in selected areas of a positive electron-beam resist on a substrate. The exposed areas have a pattern corresponding to the pattern of the required nanostructure, and dimensions of the exposed areas correspond to transverse dimensions of the nanoparticles. The exposed areas of the resist are lithographically developed, whereby a relief structure is obtained in which recesses of the profiled resist layer correspond to the locations designated for the particles. The next stage of the process is coating of the developed surface with the material of the nanoparticles, e.g., gold. The coating is carried out by sputtering. The sputtered material coats the bottoms of the recesses as well as the raised, i.e., non-developed, areas.

Method of Producing Gold Nanoparticle
US7060121
Abstract ---  A method for producing gold nanoparticles is disclosed. When gold salt solution is mixed with an absorbent, gold in the form of complexes is adsorbed onto the surface of the absorbent. The gold-loaded absorbent, after being separated from the solution by screening, filtration, settling or other methods, is ashed to form ashes. The ashes contain gold nanoparticles and impurities such as oxides of sodium, potassium and calcium. The impurities can be removed by dissolution using dilute acids. The relatively pure gold nanoparticles are obtained after the impurities are removed. Activated carbon or gold-adsorbing resin can be used as the absorbent. Silver or platinum group metal nanoparticles can also be produced by this method.

Electromagnetic Pulses Provide Pain Relief for Osteoarthritis

by Maria Seyrig

Electromagnetic pulses significantly decrease pain and inflammation associated with osteoarthritis of the knee, according to Henry Ford Hospital researchers.

In the double-blind, randomized placebo-controlled study, 34 patients used a portable battery-operated device that emits a low-intensity pulsating electromagnetic frequency and experienced more than 40 percent pain relief on their first day.

"Our results show pulsed electromagnetic fields caused a significant decrease in pain" says Fred Nelson, M.D., associate program director for research and director of the Osteoarthritis Center, Department of Orthopaedics, Henry Ford Hospital.

Dr. Nelson will present the results this week at the Orthopaedic Research Society's annual meeting in New Orleans.

Dr. Nelson explains that in the laboratory, electromagnetic signals have been shown to decrease calcium in cartilage cells. This sets off a series of chemical events that can lead to reduced inflammation. Previously, the electromagnetic fields have been used to control pain related to cosmetic surgery.

"We are really fine-tuning what we are doing to the cell environment with a very specific pulse sequence and frequency," says Dr. Nelson.

Patients strapped the small, ring-shaped plastic device around their knees for 15 minutes, twice daily for six weeks. The device was lightweight and patients could position the device directly over clothing. All participants were given a device with a coil that appeared to work but some were assigned active coils and others were given non-active coils. The electromagnetic device was developed by Ivivi Health Sciences of Montvale, New Jersey.

Osteoarthritis of the knee is a leading cause of disability and loss of independence. It is a slow, progressively degenerative disease in which the joint cartilage gradually wears away due to trauma, aging or infection. As the cartilage thins, the surrounding bone thickens and often bones rub against one another, causing additional wear. Normal activity becomes painful and difficult.

Current treatments include drug therapies like anti-inflammatory medication or pain relievers; physical therapy; support devices; health and behavioral modifications such as weight loss; surgery and joint replacement.

Dr. Nelson explains that medications often have variable success and can produce considerable side effects such as changes in kidney and liver function, a reduction in the ability of blood to clot as well as abdominal pain, nausea and indigestion.

"The exciting thing about this new approach is that it has been found to have no side effects, it is relatively low-cost in the long-run and the onset of pain relief is immediate," says Dr. Nelson. "We look at electromagnetic pulses as a potential way to improve quality of life and independence for those who suffer from osteoarthritis of the knee." Dr. Nelson says researchers will continue to look at the consistency of the relief, how long the pain relief lasts and if electromagnetic pulses might affect other joints.

Ivivi PEMF Technology Accelerates Wound Healing in Laboratory Animals, Study Reports

Ivivi Technologies, Inc.’s (AMEX: II) non-invasive, pulsed electromagnetic field (PEMF) technology increased tensile strength in a standard wound model in rats by 59% after 21 days, researchers reported in the August 2007 journal of Plastic and Reconstructive Surgery. The study was conducted at the Montefiore Medical Center, in The Teaching Hospital of the Albert Einstein College of Medicine in New York. PEMF signals have accelerated the physiological processes involved in healing in multiple clinical studies.

“PEMF signals accelerate biomechanical wound healing. These wounds healed faster and were stronger, earlier, than those that weren’t treated,” said Dr. Berish Strauch, of the Department of Plastic and Reconstructive Surgery at Albert Einstein, in whose lab the study was done. “This study represents the first objective data on the effect of PEMF on healing rates of cutaneous wounds at the cellular level. Although the mechanisms of action are not fully known, previous studies have shown that PEMF enhances the production of wound healing factors that reduce the time of the inflammatory phase as well as accelerates the production of the animal’s own growth factors including Vascular Endothelial Growth Factor (VEGF), which modulates new blood vessel growth. This study shows that a specifically configured PEMF signal yields the best result.”

“As we get a clearer picture of the transduction properties of the physiological pathways involved in tissue repair, we can configure new PEMF signals,” said Dr. Arthur Pilla, Professor of Biomedical Engineering at Columbia University, Ivivi Science Director, and a co-author of the study. “We are increasingly able to fine-tune the configuration of PEMF signals to achieve a more optimal ‘dose’ for different indications, as evidenced in this study.” Dr. Pilla invented the bone-growth stimulator, an early medical application of PEMF technology.

“If a patient can be discharged earlier after surgery, not only can that patient return to an active lifestyle more rapidly, but healthcare costs can be reduced,” commented Andre’ DiMino, Vice Chairman and Co-CEO of Ivivi Technologies, Inc. “Thus, if we can increase the strength of a wound at an earlier stage in the postoperative period, we can offer an absolute improvement on patient outcomes with a simple non-invasive technology with no known side effects.”

About The Study

The study involved 100 rats, each with a linear skin incision on their dorsum that was subsequently sutured and treated with non-invasive PEMF signals. The study was prospective, placebo-controlled and double blinded and designed to test different PEMF signal configurations for 21 days. Four different signals were used targeting the calcium/calmodulin pathway which is at the start of the anti-inflammatory and growth factor stages of tissue repair. PEMF has been shown to accelerate the binding of calcium to calmodulin. At the end of the 21 day period, one specific signal had the most significant effect on wound repair, demonstrating a 59% increase in wound tensile strength compared to control, leading researchers to conclude that exposing wounds to PEMF of very specific configurations accelerated wound repair in the early, most critical phases of healing in this animal model.

OsteoPad Bone Hardener

This unique invention relates to the field of electrotherapy, bioelectricity, bioelectromagnetics, sports performance enhancement, medical electricity and electromedicine. Particularly, the invention involves the novel implementation of electrotherapy for those suffering from osteopenia or osteoporosis. This amazing product comprises the specific, patented signal for resonating with the bone calcium channels to open them for transport across the cell membrane, thus simulating the performance of weight-bearing exercise. Its patents have expired but the three medical doctors never created the present product though all three Drs. Robert Becker, Andrew Bassett, and Arthur Pilla knew it will prevent and reverse osteoporosis from clinical trials and numerous journal articles. However, they claim that no "funding" ever arrived for creating the consumer electrotherapy unit which we now call the "OsteoPad". It is easy to use, with a flat pancake magnetic coil in a pad connected to the simple control panel which can be set on the nightstand for all-night treatments. This product will no doubt be a great seller since "1 out of every 2 people" in the US suffers or will suffer from bone loss as they age, which is called osteoporosis since the bones become porous without weight-bearing exercise to stimulate the piezoelectric bone to open calcium channels naturally. The OsteoPad signal does the work for the elderly person and lets their bones absorb calcium and magesium directly. - Available in early 2014

Non-Thermal Radio Frequency and Static Magnetic Fields Increase Rate of Hemoglobin Deoxygenation in a Cell-Free Preparation

David Muehsam, et al.
 
Abstract -- The growing body of clinical and experimental data regarding electromagnetic field (EMF) bioeffects and their therapeutic applications has contributed to a better understanding of the underlying mechanisms of action. This study reports that two EMF modalities currently in clinical use, a pulse-modulated radiofrequency (PRF) signal, and a static magnetic field (SMF), applied independently, increased the rate of deoxygenation of human hemoglobin (Hb) in a cell-free assay. Deoxygenation of Hb was initiated using the reducing agent dithiothreitol (DTT) in an assay that allowed the time for deoxygenation to be controlled (from several min to several hours) by adjusting the relative concentrations of DTT and Hb. The time course of Hb deoxygenation was observed using visible light spectroscopy. Exposure for 10–30 min to either PRF or SMF increased the rate of deoxygenation occurring several min to several hours after the end of EMF exposure. The sensitivity and biochemical simplicity of the assay developed here suggest a new research tool that may help to further the understanding of basic biophysical EMF transduction mechanisms. If the results of this study were to be shown to occur at the cellular and tissue level, EMF-enhanced oxygen availability would be one of the mechanisms by which clinically relevant EMF-mediated enhancement of growth and repair processes could occur...

...Although much further work is required to ascertain the clinical relevance of the results reported here, enhanced oxygen delivery using PRF or SMF may be important non-invasive, non-pharmacologic therapeutic modalities by which clinically relevant EMF-mediated enhancement of growth and repair processes can occur.

Electromagnetic fields instantaneously modulate nitric oxide signaling in challenged biological systems.

A. Pilla

Abstract -- This study shows that a non-thermal pulse-modulated RF signal (PRF), configured to modulate calmodulin (CaM) activation via acceleration of Ca(2+) binding kinetics, produced an immediate nearly 3-fold increase in nitric oxide (NO) from dopaminergic MN9D cultures (P < 0.001). NO was measured electrochemically in real-time using a NO selective membrane electrode, which showed the PRF effect occurred within the first seconds after lipopolysaccharide (LPS) challenge. Further support that the site of action of PRF involves CaM is provided in human fibroblast cultures challenged with low serum and exposed for 15 min to the identical PRF signal. In this case a CaM antagonist W-7 could be added to the culture 3 h prior to PRF exposure. Those results showed the PRF signal produced nearly a two-fold increase in NO, which could be blocked by W-7 (P < 0.001). To the authors' knowledge this is the first report of a real-time effect of non-thermal electromagnetic fields (EMF) on NO release from challenged cells. The results provide mechanistic support for the many reported bioeffects of EMF in which NO plays a role. Thus, in a typical clinical application for acute post operative pain, or chronic pain from, e.g., osteoarthritis, EMF therapy could be employed to modulate the dynamics of NO via Ca/CaM-dependent constitutive nitric oxide synthase (cNOS) in the target tissue. This, in turn, would modulate the dynamics of the signaling pathways the body uses in response to the various phases of healing after physical or chemical insult or injury.

A pulsing electric field (PEF) increases human chondrocyte proliferation through a transduction pathway involving nitric oxide signaling.

Fitzsimmons RJ1, Gordon SL, Kronberg J, Ganey T, Pilla AA.

Abstract -- A potential treatment modality for joint pain due to cartilage degradation is electromagnetic fields (EMF) that can be delivered, noninvasively, to chondrocytes buried within cartilage. A pulsed EMF in clinical use for recalcitrant bone fracture healing has been modified to be delivered as a pulsed electric field (PEF) through capacitive coupling. It was the objective of this study to determine whether the PEF signal could have a direct effect on chondrocytes in vitro. This study shows that a 30-min PEF treatment can increase DNA content of chondrocyte monolayer by approximately 150% at 72 h poststimulus. Studies intended to explore the biological mechanism showed this PEF signal increased nitric oxide measured in culture medium and cGMP measured in cell extract within the 30-min exposure period. Increasing calcium in the culture media or adding the calcium ionophore A23187, without PEF treatment, also significantly increased short-term nitric oxide production. The inhibitor W7, which blocks calcium/calmodulin, prevented the PEF-stimulated increase in both nitric oxide and cGMP. The inhibitor L-NAME, which blocks nitric oxide synthase, prevented the PEF-stimulated increase in nitric oxide, cGMP, and DNA content. An inhibitor of guanylate cyclase (LY83583) blocked the PEF-stimulated increase in cGMP and DNA content. A nitric oxide donor, when present for only 30 min, increased DNA content 72 h later. Taken together, these results suggest the transduction pathway for PEF-stimulated chondrocyte proliferation involves nitric oxide and the production of nitric oxide may be the result of a cascade that involves calcium, calmodulin, and cGMP production.

Nitric oxide mediates the effects of pulsed electromagnetic field stimulation on the osteoblast proliferation and differentiation.

Diniz P1, Soejima K, Ito G.

Abstract -- The purpose of this research was to investigate whether the effects of pulsed electromagnetic field (PEMF) stimulation on the osteoblast proliferation and differentiation are mediated by the increase in the nitric oxide (NO, nitrogen monoxide) synthesis. The osteoblasts (MC3T3-E1 cell line) were cultured in the absence (-NMMA group) or in the presence (+NMMA group) of the NO synthase inhibitor L-NMMA. First, osteoblasts were subjected to PEMF stimulation (15 Hz and 0.6 mT) up to 15 days. The DNA content and the NO concentration in the conditioned medium were determined on the 3rd, 7th, and 15th days of culture. Following, osteoblasts were stimulated in the proliferation (P-NMMA and P+NMMA groups) or in the differentiation (D-NMMA and D+NMMA groups) stages of maturation, and the alkaline phosphatase (AlPase) activity was determined on the 15th day of culture for all groups. PEMF stimulation increased significantly the nitrite concentration in the -NMMA group on the 3rd, 7th, and 15th days of culture. However, this effect was partially blocked in the +NMMA group. The DNA content in the -NMMA group, but not in the +NMMA group, increased significantly on the 3rd and 7th days of culture. The AlPase activity in the P-NMMA and D-NMMA groups, but not in the P+NMMA and D+NMMA groups, also increased significantly. In conclusion, the PEMF stimulatory effects on the osteoblasts proliferation and differentiation were mediated by the increase in the NO synthesis.

Sinusoidal electromagnetic field stimulates rat osteoblast differentiation and maturation via activation of NO-cGMP-PKG pathway.

Cheng G1, Zhai Y, Chen K, Zhou J, Han G, Zhu R, Ming L, Song P, Wang J.

Abstract -- Nitric oxide (NO) is an important intracellular and intercellular messenger, critically affecting bone metabolism. The purpose of this research is to investigate whether the effect of sinusoidal electromagnetic field (SEMF) on the differentiation and maturation of osteoblasts is mediated by the NO-cGMP-PKG signal pathway. We examined the impact of SEMF on nitric oxide synthase (NOS) activity, and found that L-NAME, nitric oxide synthase's inhibitor, prevents SEMF-mediated increase in NOS activity and NO levels. We showed that an inhibitor of soluble guanylyl cyclase (ODQ) blocks the increase in cGMP levels triggered by exposure to SEMF. The inhibitor PDE5, which hydrolyzes 3',5'-cyclic-GMP to 5'-GMP, prevents the SEMF's stimulation of PKG activity. We also blocked the NO-cGMP-PKG pathway to determine whether the maturation and mineralization of osteoblasts, stimulated by SEMF, would be inhibited. This was evaluated by measuring alkaline phosphatase (ALP) activity, osterix gene expression and mineralized bone modulus. After treatment with SEMF, the NOS activity increases in comparison with the control group (P<0.01), reaching the highest level after 0.5h. Osterix gene expression, ALP activity and mineralized bone nodules in the SEMF experimental group also increase significantly. However, these effects are partially blocked in the L-NAME treated cultures. Surprisingly, all the osteogenic markers in the SEMF+L-NAME group were slightly higher than in the control culture, but lower than in the cells exposed to SEMF only. We conclude that the NO-cGMP-PKG signal pathway is activated by SEMF treatment, the stimulatory effect of SEMF on the differentiation and mineralization of osteoblasts is attenuated when the pathway is blocked.

Reducing blood viscosity with magnetic fields.

Tao R1, Huang K.

Abstract -- Blood viscosity is a major factor in heart disease. When blood viscosity increases, it damages blood vessels and increases the risk of heart attacks. Currently, the only method of treatment is to take drugs such as aspirin, which has, however, several unwanted side effects. Here we report our finding that blood viscosity can be reduced with magnetic fields of 1 T or above in the blood flow direction. One magnetic field pulse of 1.3 T lasting ~1 min can reduce the blood viscosity by 20%-30%. After the exposure, in the absence of magnetic field, the blood viscosity slowly moves up, but takes a couple of hours to return to the original value. The process is repeatable. Reapplying the magnetic field reduces the blood viscosity again. By selecting the magnetic field strength and duration, we can keep the blood viscosity within the normal range. In addition, such viscosity reduction does not affect the red blood cells' normal function. This technology has much potential for physical therap

Effects of mobile phone radiofrequency on the structure and function of the normal human hemoglobin.

Mousavy SJ1, Riazi GH, Kamarei M, Aliakbarian H, Sattarahmady N, Sharifizadeh A, Safarian S, Ahmad F, Moosavi-Movahedi AA.

Abstract -- Widespread use of mobile phones has increased the human exposure to electromagnetic fields (EMFs). It is required to investigate the effect of EMFs on the biological systems. In this paper the effect of mobile phone RF (910MHz and 940 MHz) on structure and function of HbA was investigated. Oxygen affinity was measured by sodium dithionite with UV-vis spectrophotometer. Structural changes were studied by circular dichroism and fluorescence spectroscopy. The results indicated that mobile phone EMFs altered oxygen affinity and tertiary structure of HbA. Furthermore, the decrease of oxygen affinity of HbA corresponded to the EMFs intensity and time of exposure.

EMF signals and ion/ligand binding kinetics: prediction of bioeffective waveform parameters.

Pilla AA1, Muehsam DJ, Markov MS, Sisken BF.

Abstract -- The kinetics of an electromagnetic field (EMF) target pathway are used to estimate frequency windows for EMF bioeffects. Ion/ligand binding is characterized via first order kinetics from which a specific electrical impedance can be derived. The resistance/capacitance properties of the binding pathway impedance, determined by the kinetics of the rate-determining step, define the frequency range over which the target pathway is most sensitive to external EMF. Applied signals may thus be configured such that their spectral content closely matches that of the target, using evaluation of the signal to thermal noise ratio to optimize waveform parameters. Using the approach proposed in this study, a pulsed radio frequency (PRF) waveform, currently employed clinically for soft tissue repair, was returned by modulation of burst duration, producing significant bioeffects at substantially reduced signal amplitude. Application is made to Ca2+/Calmodulin-dependent myosin phosphorylation, for which the binding time constants may be estimated from reported kinetics, neurite outgrowth from embryonic chick dorsal root explants and bone repair in a fracture model. The results showed that the retuned signal produced increased phosphorylation rates, neurite outgrowth and biomechanical strength that were indistinguishable from those produced by the clinical signal, but with a tenfold reduction in peak signal amplitude, approximately 800-fold reduction in average amplitude and approximately 10(6)-fold reduction in average power.

Pulsed magnetic fields accelerate cutaneous wound healing in rats.

Strauch B1, Patel MK, Navarro JA, Berdichevsky M, Yu HL, Pilla AA.

Abstract -- Previous studies of pulsed magnetic fields have reported enhanced fracture and chronic wound healing, endothelial cell growth, and angiogenesis. This study characterizes the biomechanical changes that occur when standard cutaneous wounds are exposed to radiofrequency pulsed magnetic fields with specific dosage parameters, in an attempt to determine whether return to functional tensile strength could be accelerated in wound healing.

The mean tensile strength of treated groups in phase 1 was 48 percent (p < 0.001) greater than that of controls at 21 days; there was no significant difference at 60 days. In phase 2, the treated groups showed 18 percent (not significant), 44 percent, and 59 percent (p < 0.001) increases in tensile strength over controls at 21 days.

The authors successfully demonstrated that exposing wounds to pulsed magnetic fields of very specific configurations accelerated early wound healing in this animal model, as evidenced by significantly increased wound tensile strength at 21 days after wounding.

Pulsed magnetic field therapy increases tensile strength in a rat Achilles' tendon repair model.

Strauch B1, Patel MK, Rosen DJ, Mahadevia S, Brindzei N, Pilla AA.

Abstract -- To examine the effect of pulsing electromagnetic fields on the biomechanic strength of rat Achilles' tendons at 3 weeks after transection and repair.

In the animals receiving PMF exposure, an increase in tensile strength of up to 69% was noted at the repair site of the rat Achilles' tendon at 3 weeks after transection and repair compared with nonstimulated control animals.

The application of electromagnetic fields, configured to enhance Ca(2+) binding in the growth factor cascades involved in tissue healing, achieved a marked increase of tensile strength at the repair site in this animal model. If similar effects occur in humans, rehabilitation could begin earlier and the risk of developing adhesions or rupturing the tendon in the early postoperative period could be reduced.
