Abstract

This paper proposes a general finite element approach for the frequency-domain homogenization of electromagnetic periodical structures. Based on local finite element resolutions on a cell, the method allows taking into account the local effects at the macroscopic level through the determination of equivalent macroscopic permeability and conductivity laws. Examples of the modeling of eddy current losses in windings are presented.
