A Mathematical approach to loss estimation in non-homogeneous magnetic materials

The paper deals with thye application of the homogenization technique to the electromagnetic analysis of nonhomogeneous materials compoed of grains bounded by a layer whose electric and magnetic characteristics are sensibly different. The investigation is performed by comparing local and integral quantities, provoded by the proposed approach with the results given by a standard finite element solution, which requires a significantly higher processing time. The ionfluence of different geomatrical and constitutive parameters and the merits and limits of the method are finellty discussed.
