Circuit Modeling Technique for Electrically-Very-Small Devices Based on Laurent Series Expansion of Self-/Mutual Impedances

Abstract

This paper proposes a circuit modeling technique for electrically-very-small devices, e.g. electrodes for intrabody communications, coils for wireless power transfer systems, high-frequency transformers, etc. The proposed technique is based on the method of moments and can be regarded as an improved version of the partial element equivalent circuit method.
