The effective dielectric function of a granular medium, where the inclusions have spheroidal symmetry, is studied by means of a renormalized polarizability theory (RPT) that takes into account the local field fluctuations due to the inhomogeneity of the system. We examine as well the reaches and limitations of an empirical model that includes the percolation phenomena within the mixing rules through the RPT.
