Comparison of FEM-PEEC Coupled Method and Finite-Element Method

This paper analyzes the efficiencies of the new coupling between finite-element methods (FEMs) and the partial element equivalent circuit method (PEEC), which are computation time and memory space. To show its performance, a common mode filter is modeled by the coupling and the results are then compared with those of a FEM analysis. The comparison shows that the coupling is very efficient to model electromagnetic systems comprising magnetic materials and systems of complex thin conductors.
