Волноводные характеристики полупроводниковых комплектующих электрорадиоизделий при наличии потока заряженных частиц

Abstract

A new mechanism of initiation of surface at uneven of the conducting solid bodies is proposed. The development of theory of interaction of microwave electromagnetic oscillations and charged particles in bounded plasma-like media and the study of kinetic and hydrodynamic beam instabilities in solid –like structures appled in the present microwave electronics is proposed. The power losses of the flow of charged particles caused by such an interaction due to excitation of surface polaritons in the semiconductor superstructure have been determined. The influence of pulsed electromagnetic radiation on electric radio apparatus is often accompanied by currents arcsing on inner current – conducting elements as well as by the distortion of their internal fields. A theory of collisionless damping of surfaceplasmons in qvantium and classical approcsimations is tlfborated and the conditions of its conversion are determined. The effect of inhomogeneouse properties of surface of open radiating structures on the spectral characteristics of transition radiation is studies. It is found that thte energy losses related to excitation of volume helicons are equivalent to the energy losses of a magnetic moment created due to the charge rotation. New mechanism of excitation of surface magnitoplasmf oscillations by the moving radiation source are suggested.
