In this paper, a review on dielectric mixtures and the importance of the
numerical simulations of dielectric mixtures are presented. It stresses on the
interfacial polarization observed in mixtures. It is shown that this
polarization can yield different dielectric responses depending on the
properties of the constituents and their concentrations. Open question on the
subject are also introduced.Comment: 40 pages 12 figures, to be appear in IEEE Trans. on Dielectric
