The Use of Simulation Models for Complex Description of Permittivity of Building Materials

Abstract

Distribution function of relaxation time mathematically describes frequency dependence of the complex permittivity. Empirical function describing the complex permittivity in the frequency domain needs to be broken down to real and imaginary part, and thus separated. The permittivity is a function of the frequency of the electric field and describes behavior of technical dielectric in an alternating electric field. In this case the dielectric is a building material. The paper describes application of simulation models with variable distribution parameters and relaxation time.
