Semiconductors with ellipsoidal and non‐parabolic energy bands are considered. A relaxation time of tensor character is assumed. The solution of the transport equation obtained by Zukotynski and Grynberg [1], is generalized to include a time‐dependent electric field. The results are then used in the Maxwell equations and the condition of minimum reflection is obtained. Both the Faraday and Voigt configurations in a small magnetic field are considered. The position of the plasma minimum is found to depend on the state of polarization of the incident radiation with respect to the energy surfaces.
