Abstract:
A handheld atmospheric pressure glow discharge plasma source is provided without the use of an arc. The plasma is induced using a radio frequency signal. An LC resonator in the handheld source with a gain of about 10 at 13.56 MHZ improves the power transfer from a power supply and tuner to the plasma chamber which is capable of producing stable plasmas in Ar, He and O.sub.2 mixtures.
Abstract:
A method for producing stable atmospheric pressure glow discharge plasmas using RF excitation and the use of said plasmas for modifying the surface layer of materials. The plasma generated by this process and its surface modification capability depend on the type of gases used and their chemical reactivity. These plasmas can be used for a variety of applications, including etching of organic material from the surface layer of inorganic substrates, as an environmentally benign alternative to industrial cleaning operations which currently employ solvents and degreasers, as a method of stripping paint from surfaces, for the surface modification of composites prior to adhesive bonding operations, for use as a localized etcher of electronic boards and assemblies and in microelectronic fabrication, and for the sterilization of tools used in medical applications.

Abstract:
The present invention is directed to systems and methods for radiating radar signals, communication signals, or other similar signals. In one embodiment, a system includes a controller that generates a control signal and an antenna coupled to the controller. The antenna includes a first component that generates at least one wave based on the generated control signal and a metamaterial lens positioned at some predefined focal length from the first component. The metamaterial lens directs the generated at least one wave.
