Abstract
Metamaterials whose individual components are coupled by magnetic induction have been considered as power transfer media previously. Here we explore a new structure to overcome their major limitations of limited coupling strength and attenuation - the Capacitor Coupled Grid (CCG) where electric coupling mediated by using capacitors. This paper reports an investigation of CCG power transfer system with resonant transmitter and receiver terminals. The optimal power transfer efficiency conditions and the optimal terminal design is discussed in this study.
