Abstract:
A theoretical study is presented of the modulation of high-frequency radio waves in amplitude and phase by causing them to be reflected from an n-type semiconductor slab while periodically varying the temperature of the carriers. An opportunity to control with heat the angle of total polarization of the reflected waves is reported. It is demonstrated that the amplitude, phase and polarization of the reflected signals can be varied fast enough for the evolution of these processes to be controlled in rapidly adaptive optical devices in the high frequency range.
