Universal Dielectric Response of Atmospheric Ice Using COMSOL Multiphysics®
Publié en 2013
Heterogeneous materials with different phases, are conductive and insulating (dielectric), and are physically present in different natural materials as e.g. atmospheric ice. Jonscher’s proposed ‘universal dielectric response’ is not sufficient for such materials, as it only reflects conductivity as a nonlinear function of frequency, whereas at lower temperatures dipolar vibrations are also very sensitive to temperature. In this paper an analytical equation of conductivity as a function of frequency and temperature is used but is shown implicitly which is numerically solved using Comsol. The results are then compared with the experimentally determined conductivity values of atmospheric ice.
