Finite-Element Simulation of the Depolarization Factor of Arbitrarily Shaped Inclusions

THE MAIN goal of this paper is the depolarization factor (DF) of arbitrarily shaped polarizable inclusion in 2-D heterostructures. Since analytical calculation of the response of an arbitrary composite material is typically intractable, numerical simulation is the standard method to extract the effective properties of these complex media. For that purpose we use a finite-element (FE) methodology to derive the effective permittivity of the mixed medium. As an illustrative application of this tech
