Abstract

Statistic and matrix mixtures were modelled using a FEM based software from the ANSOFT Corporation and their static permittivity was computed. The study presented in this paper emphasizes the influence that shapes, dimensions, distances between particles, filling factor and space distribution of inclusions have upon the static average permittivity of the composite dielectrics. The results of the computations are compared with analytical solution obtained from well-known formulas..
