Abstract

A methodology for improving efficiency of wireless power transfer (WPT) systems, derived from the concept of conjugate image impedances, is presented. For accuracy reasons, enhancement of the system efficiency through adjustment of its geometry parameters is based on full-wave electromagnetic (EM) simulation models. Fast WPT system design is realized by means of surrogate-based optimization exploiting auxiliary equivalent network model, frequency scaling and response correction techniques.
