On a thermodynamical model for dielectric relaxation phenomena

In this paper an extension of Debye's model by considering Kluitenberg's theory on dielectric relaxation phenomena is proposed. Following Kluitenberg's dielectric theory, it is supposed that the phenomenological coefficient of the second derivative of differential equation governing the dielectric phenomena is not constant. In particular, by identifying some coefficients of the Kluitenberg differential equation on dielectric relaxation to those of Debye's one, an expression for storage and loss dielectric constants as the sum of Debye's relation and a function which depends on the frequency ω and the aforementioned coefficient can be obtained. Its physical meaning allows us to use it for fitting experimental data.
