Passive-Element Circuit Model of a Wireless Power Transfer System

Abstract (in Japanese) (See Japanese page) 
(in English) The impedance expansion method (IEM) is a circuit modeling technique for electrically very small devices based on the method of moments. In the authors' previous work, a circuit model of wireless power transfer systems was obtained by utilizing the IEM and eigenmode analysis. However, there remains difficulty in analyzing the model on versatile circuit simulators because it employs dependent voltage sources proportional to the powers of the frequency to represent the radiation loss. In this report, a circuit model that approximates the dependent voltage sources only by passive elements (passive-element circuit model) is described.
