Abstract:
Feasibility of controlled modulation of VHF radio waves is shown by means of reflecting waves from the surface of an n-type semiconductor with a periodically varying carrier temperature. Heating of the carriers by an external electric field is discussed, and cases of amplitude modulation and polarization of waves passing through the semiconductor plate are considered. The role of external magnetic fields in the formation of the polarization structure of radiation is noted.
