INDOOR WIRELESS POWER TRANSFER USING ASYMMETRIC DIRECTLY-STRONG-COUPLING MECHANISM

This letter proposes a new wireless power transfer mechanism named the directly-strong-coupling. It adopts only two resonators and it achieves strong-coupling performances. Asymmetric sizes of antennas are designed to reduce the receiver's size for indoor applications. The mechanism remains a power efficiency of 35.6% over a distance of 1 m.
