Abstract

Soil as a complex multi-phase porous material typical exhibits several distributed relaxation processes in the frequency range from 1 MHz to approximately 10 GHz of interest in applications. To relate physico-chemical material parameters to the dielectric relaxation behavior, measured dielectric relaxation spectra have to be parameterized. In this context, a broadband numerical 3D FEM study was carried out to analyze the possibilities and limitations in the characterization of the relaxation processes in complex systems.
