A theoretical investigation is made of the case of normal incidence of a linearly polarized electromagnetic wave upon a donor semiconductor to which a heating electric field F and a magnetic field H is applied. The impurity concentration is determined by the law N ( z ) = N 0 + N 1 cos qz . The wave inside the semiconductor splits into two waves with circular polarizations. Near the Bragg resonance, which can occur only for one of these two waves having the wave vector k ≈ q /2, some peculiarities appear in the reflection and the transmission of this wave. It is shown that the reflection and the transmission coefficients as well as polarization of the resulting wave can be considerably influenced by means of the magnetic and the electric fields.
