3-D Semi-Analytical Homogenization Model for Soft Magnetic Composites

A 3-D semi-analytical homogenization model for soft magnetic composites (SMCs) is presented. The model is able to handle the nonlinear magnetic behavior of the ferromagnetic particles and estimate the eddy current (EC) losses. Comparisons to finite element (FE) results show a very good agreement for a unit cell of composite. The model can be used in a structural FE study of electromagnetic devices made of SMCs.
