Circuit Modeling of Wireless Power Transfer Systems Using Impedance Expansion Method (Invited Paper)

Abstract

The impedance expansion method (IEM) is a circuit modeling technique based on the method of moments. The IEM has been extended mainly for application to wireless power transfer systems. For example, the IEM has been extended to consider the presence of perfectly conducting and dielectric/magnetic scatterers. This paper introduces the basic concept, theoretical extension, and recent application of the IEM.
