Theoretical calculations of the Maxwell‐Wagner polarization are performed by considering thermodynamic equilibrium conditions. The model applied consists of a spherical void inside an ionic matrix of NaCl type containing charge carriers (cation and anion vacancies) subjected to the action of an external dc electric field. Accurate analytical solutions obtained for the stationary state describes i) the distribution of the charge carriers in the vicinity of void and ii) the distribution of potential and electric field both, inside the void and in the crystal matrix.
