This article proposes a method based on 3-D discrete element and finite element methods to numerically evaluate the effects of the particle size distribution of soft magnetic composite (SMC) on the electromagnetic property. The three SMC models which obey Gaussian, homogeneous, and twin-peak distributions are compared using the proposed method. It is shown that the Gaussian model has the highest permeability and the lowest loss at high frequencies under the condition that the three models have the same filling rate.
