Small-Signal Impedance of a Radio Frequency Plasma Capacitor
A capacitor for radio frequency control is proposed that uses a gas discharge plasma as a variable dielectric. Experimental small-signal impedance measurements on a prototype device at 500 MHz-2.4 GHz show a capacitance ratio of 2-6:1 with a quality factor of 60 at 600 MHz. Results compare well with simple theoretical descriptions of the dielectric properties of plasmas.
