Corrections to the power-law dependence of ac conductivity in ion-conducting materials due to “electrode polarization” effect

Abstract: Based on the supposition related to fractal nature of transport processes in disordered media new expression for the low-frequency ac conductivity dependence was obtained. New expression for the ac conductivity generalizes the conventional and the so-called “universal” power-law dependence and gives a possibility to take into account the influence of the electrode polarization effect. The ac conductivity expression obtained is in excellent agreement with available experimental data for a wide frequency range.
