Microwave Radiation from a Plasma in a Magnetic Field (II)

Abstract

The microwave radiation from a dc discharge plasma in a magnetic field was studied. The experimental results showed that the resonant radiations of the ordinary wave, propagating perpendicular to a magnetic field, were observed near the electron cyclotron harmonics. The number of the successive harmonics increased with decreasing the gas pressure, independently of the kind of gas used. The characteristics of these radiations were very similiar to those of the extraordinary wave. Such cyclotron harmonics were discussed by the dispersion relation.
