Peculiarities of electron-wave interactions in the resonance system with a semiconductor

The method of multifunctional scheme creation using wave phenomena in semiconductors and the search of new physical principles of generation, amplification, and electromagnetic wave transformation in the development of mm and sub-mm range semiconducting devices is considered. This report deals with electron-wave interactions in an active spatial-periodical semiconducting system placed in longitudinal electrical and strong magnetic fields. The key element of the electrodynamical model of the system under consideration is an h thickness semiconducting sample with a spatial-periodical structure having the period 1. By virtue of the system nonequilibrium, the spatial charge disturbances arising in the semiconductor propagate in the form of electrokinetic waves which are transformed, in their turn, into electromagnetic radiation, a part of which interacts again with the carriers and so on
