Current cancer treatments such as surgery, radiation and chemotherapy have significant side-effects for the patients. New treatments are being developed to reduce these side-effects while giving doctors alternative methods to treat patients. This invention introduces a new method for treatment of malignant tumors including brain cancer, pancreatic cancer, lung cancer, and ovarian cancer. The method uses low-power RF wave to disrupt and kill cancer cells during mitosis resulting in shrinking the size of solid tumors. Direction of polarization of the electric field of the RF wave relative to the axis of division of the cancer cells has an impact on the ability of the RF wave in disrupting mitosis and killing the cancer cells. Since the orientation of the cancer cells in a tumor are random a method is needed to change the orientation of the applied RF wave spatially with time to maximize elimination of the cancer cells.

In biological tissues, exposure to electromagnetic fields usually induces actuation and vibration of the underlying molecules which, from the perspective of the electromagnetic device, manifests as power absorption. It has been shown that increased power absorption of a low-power RF source can have positive enhancement in therapeutic, medical, and scientific procedures. However, often the enhanced power absorption is limited due to the electromagnetic properties of the tissue being treated. This invention introduces a method to modify the native electromagnetic properties of a targeted biological tissue to increase and enhance the electromagnetic power absorption within and increase treatment efficacy.

Current cancer treatments such as surgery, radiation and chemotherapy have significant side-effects for the patients. New treatments are being developed to reduce these side-effects while giving doctors alternative methods to treat patients. This invention introduces a new apparatus for treatment of malignant tumors including brain cancer, pancreatic cancer, lung cancer, ovarian cancer, and breast cancer. The apparatus couples RF power into the tumor using evanescent waves. The evanescent waves disrupt the division of cancer cells causing the cancer cells to die and shrink the size of the tumor. Due to the targeted approach of the evanescent waves, less RF energy is wasted in healthy cells.

An antenna assembly configured to be mounted on a glass structure. The antenna assembly comprises a multilayer structure comprising i) a superstrate layer comprising a thin dielectric material; ii) an antenna layer on which the superstrate layer is disposed, the antenna layer comprising an electrically conducting material; and ii) a first substrate layer on which the antenna layer is disposed. The antenna assembly further comprises a housing in which the multilayer structure is disposed. The housing is adapted for attachment to a surface of the glass structure. A dielectric characteristic of the superstrate layer compensates for a dielectric characteristic of the glass structure in order to reduce the variability of the operating frequency of the antenna assembly.

A system of modular multi-aperture reflector sheets for use in general and specialty luminaires is disclosed. These sheets, designed to be simple in design, manufacture, and installation, allows for enhancing, adjusting, varying, or correction of the light distribution provided by luminaires during production or deployment. The reflector sheets are made of highly-reflective, thin material and feature multiple apertures that are patterned to redirect the light output emerging from the output of a luminaire. The reflector sheets are intended to be used in combination with both standard and custom reflectors and replace complicated and expensive lenses and optics that are often deployed to modify luminaire light distribution. The sheets are modular and can be replaced easily, allowing for standard luminaires having multiple possible light distribution patterns without further complication. Also, custom multi-aperture reflector sheets can be designed, shipped, and installed easily if further modification or correction of the light distribution is desired.

Electrodeless high intensity discharge (HID) lamps have the promise of higher reliability and higher efficiency than traditional electroded high intensity discharge lamps. However, most electrodeless HIDs operate in the frequency range of around 400 MHz or higher resulting in expensive, inefficient RF drivers that reduce the overall efficacy of the lamp. Operating the lamp at lower frequencies results in substantial increase in the physical dimensions of the resonators used in traditional electrodeless HIDs. In this invention a novel wave-launcher technology is used allow the lamp housing's operating frequency to be independent of the physical dimensions of the lamp housing. This provides an avenue to increase the conversion efficiency of the RF driver and the efficacy of the lamp system.

In electrodeless HID lamps the radio frequency (RF) source is separated from a lamp housing in which vessel containing plasma arc is mounted. This lamp housing is usually designed to maximize the amount of RF energy incident on the plasma arc. The plasma arc, however, cannot convert the entire amount of incident RF energy into light and a portion instead is released as propagating radiation or remains localized RF electromagnetic fields in the vicinity of lamp. In this invention, we introduce field suppression probes: Small, configurable structures that are made of conductive materials that mount directly to the lamp housing or alternately the lamp fixture that is able to suppress unused RF energy that is emanated from the lamp housing or plasma. These probes, when configured with the lamp, can substantially suppress the unused RF energy and prevent EMI emissions and reduce RF feedback that can adversely affect the lamp.

A novel compact air-cavity electrodeless high intensity discharge lamp is disclosed that provides added flexibility in its design to improve performance and reliability. A coupling sleeve surrounds a bulb assembly that can replace the output coupling element require for effective operation of the lamp. The coupling sleeve couples the RF energy from the input coupling element to the bulb and the bulb assembly serves to provide the heat sinking needed for the bulb to operate within the temperature range necessary to achieve optimum performance with good reliability. Changing the design of the bulb assembly does not impact the resonant frequency of the air-cavity resonator. De-coupling the bulb assembly design from the operating frequency of the resonator gives more flexibility to designer to optimize the overall performance of the electrodeless HID lamp.

Electrodeless high intensity discharge lamps have the promise of higher reliability and higher efficiency than traditional electroded high intensity discharge lamps. However most electrodeless HIDs operate in the frequency range of around 400 MHz to 2.5 GHz resulting in expensive, inefficient RF drivers that reduce the overall efficacy of the lamp. Operating the lamp at lower frequencies results in substantial increase in the size of the resonators used in traditional electrodeless HIDs. In this invention a novel design is used to lower the operating frequency of the resonator without increasing the size of the resonator. This provides an avenue to increase the conversion efficiency of the RF driver and the efficacy of the lamp system.

The present invention is directed to devices and methods for generating light with plasma lamps. More particularly, the present invention provides plasma lamps driven by a radio-frequency source without the use of electrodes inside the bulb and related methods. In a specific embodiment, a coaxial type coupling module is used to drive an electrodeless bulb. Merely by way of example, such plasma lamps can be applied to applications such as stadiums, security, parking lots, military and defense, street lighting, large and small buildings, vehicle headlamps, aircraft landing, bridges, warehouses, UV water treatment, agriculture, architectural lighting, stage lighting, medical illumination, microscopes, projectors and displays, any combination of these, and the like.
