Using a high-speed plasma as a conducting channel to enable a novel antenna approach
… for a proposed electrically short antenna using plasma with time-varying conductivity as the conducting medium was developed. The time-varying conductivity will eliminate tip reflections, allowing this conceptual antenna to radiate more efficiently at low frequencies than existing antennas. This …

Microplasma antennas: characterizing capillary plasma discharges as potential monopole antennas
This thesis investigates the use of capillary plasma elements, in glass and quartz with sub-millimeter inner diameters and 1-5 cm in length, as monopole antenna elements. Plasma elements of this size have not been demonstrated before, as most plasma antennas use fluorescent tubes with inner …

Coupled phenomena in arrays of microplasma devices and microchannel plasma devices as antennas
Arrays of microcavity and microchannel plasmas with characteristic dimensions of 25-800 micrometer have been generated in glass substrates. To reproducibly fabricate the arrays, glass micromaching using replica molding and micropowder blasting was proposed and demonstrated. The microplasmas were …

Reconfigurable antennas based on microplasma as a time-varying dielectric or conductor
… dissertation is the applications of microcavity plasmas to electromagnetically active devices in the mm-wave and µ-wave regions. There are three accomplishments reported in this dissertation: microplasma on a chip, plasma photonic crystals, and microplasma antennas. Dynamic behaviors of …
