The theory of ac conductivity and Hall mobility for solid systems which consist of anisotropic crystals with random dielectrical inclusions is developed. In the present paper we use the effective‐medium theory. The large‐frequency region, where ω < τ —1 (τ is the electron mean free time) is investigated. It is shown that in the strong frequency dispersion region both real and imaginary parts of conductivity and Hall mobility follow a power‐law behavior ω S with high anisotropic exponent S which may be used for the interpretation of experimental data in oxides.
