The ac absorption constant of an inhomogeneous semiconductor is calculated without any assumptions of electron density fluctuations to be small. A generalized Herring's method is used for calculating the effective conductivity. The method leads to a closed formula in the case of a heterogeneous two‐phase system. The presence of a maximum in the frequency dependence of absorption is explained and its connection with the system parameters is determined.
