View of one part of a wave surface for a wave being linear polarized in a plane of incidence. An electrically anisotropic medium has a parameters of a type (31), a wave corresponds to an extraordinary that. Range variation of angles is: a refraction (latitude) angle, ψ is: 0 – π (placed in a plane of Fig. 7), azimuth (longitude) angle φ is: 0 – π/2 (is oriented normally to a Fig. 7 plane)
