Relaxation Functions Interpolating the Cole–Cole and Kohlrausch–Williams–Watts Dielectric Relaxation Models

To describe non-Debye relaxation phenomena observed in dielectric materials, the Cole–Cole (CC) model frequency domain and Kohlrausch–Williams–Watts (KWW) time were introduced physics of dielectrics. In this paper, we propose a new with two parameters besides by expressing function terms Mittag–Leffler functions. The proposed represents group shows transition between CC KWW models. properties described are analyzed, including response function, normalized complex permittivity, storage loss factors as well spectral presented has concise form is expected to be applied more phenomena.
