EMC filters are increasingly integrated into power applications. To improve the filter performance it is important to model the electromagnetic interference between components to optimize their positions. In this paper, a method is proposed to construct the equivalent model of the filter components. The proposed method is based on the multipolar expansion by representing the radiation emission of generic structures in a spherical reference (r, θ, φ). These models of the sources will be used to compute the mutual inductance between the components according to their geometric placement.
