STUDY OF MICROWAVE GENERATION UTILIZING DOUBLE-STREAM INSTABILITIES IN ANISTROPIC MEDIA

Abstract

A physical basis for the amplification of an rf signal by the interaction between counterstreaming beams of negative and positive charges is presented. The description and analysis for this discrete-velocity double- stream amplification process provides a simplified analogy to the operation of the double-stream amplifier, utilizing pyrolytic graphite, under investigation. The characteristics of pyrolytic graphite that are important to the existence of double-stream instabilities are discussed. The effective masses of the holes and electrons are extremely small so that the long relaxation times required for the two-stream instability process are possible. It is shown that carrier mobilities and densities can be determined from three separate measurements.
