Metamaterial and Metasurface for Wireless Power Transfer and Magneto-Inductive Waveguide

Abstract

Metamaterials, specifically in their two-dimensional form known as metasurfaces, have emerged as a focal point of extensive investigation within contemporary scientific discourse. This chapter serves to elucidate the intricacies of the theoretical underpinnings and the practical implementation of a metasurface architecture engineered to function within the frequency domain of megahertz (MHz). The metasurface under consideration exhibits considerable promise in the realm of wireless power transfer (WPT) systems, showcasing its potential to develop this domain. Furthermore, its intrinsic ability to propagate magneto-inductive waves (MIWs) imbues it with a multifaceted utility, enabling its application in diverse scenarios such as near-field information transmission and the development of structures that facilitate the simultaneous conveyance of both energy and information.
