An extension of the unstructured partial element equivalent circuit (PEEC) method to magnetic media is proposed. Linear inhomogeneous conductive, dielectric, and magnetic media are considered.

Abstract
An extension of the unstructured partial element equivalent circuit (PEEC) method to magnetic media is proposed. Linear inhomogeneous conductive, dielectric, and magnetic media are considered. By formulating PEEC in terms of div-free currents, an efficient circuit algorithm based on the independent loop search or basis reduction scheme can be used to solve the electromagnetic problem. In such a way, a limited number of unknowns can be used and non-simply connected domains can be treated as well. The formulation is validated on a real integrated inductor, capacitor, and transformer (L-C-T) component against measurements and numerical results from commercial software based on integral equation method and finite element method.Pubblicazioni consigliate
