Abstract

A typical wireless energy or data transfer system consists of two inductors that are coupled through the mutual magnetic field. The performance of the system is determined by the k coupling factor which represents the linkage between the two coils. The paper introduces a new method for the calculation of the coupling factor in a time efficient way using the sensitivity parameter.
