Dielectric relaxation and dielectric mixtures: similarities

Spectral density representation is a tool to analyze electrical properties of material mixtures and the geometrical description of the system. The aim of this paper is to derive an expression for the spectral density representation, which favors dielectric relaxation phenomenon. This unfamiliar form is distinct in a way that the existing dielectric relaxation models and data analysis tools can be employed for extracting the spectral density function of a given system.
