The Interaction of Microwaves with Gas-Discharge Plasmas

The interaction of microwaves with gas-discharge plasmas provides a valuable tool for studying the fundamentals of gas-discharge phenomena and methods of controlling and switching microwave power. A summary of our present state of knowledge in this field is presented by using as particular examples the interaction of high density and low density gas-discharge plasmas in S-band resonant cavities, both in the presence and absence of dc magnetic fields.
