Microstripline Circuits for Microwave Plasma Discharges

IntroductionWidely used in a variety of products and processes, plasmas are generated by applying a voltage between electrodes to facilitate gas ionization. The voltage may be static (DC) or varying at a fixed rate that can be in the RF range (<100 KHz) or as high as tens of MHz in frequency. Typical plasmas have a characteristic physical dimension...
