Abstract
This study presents the metamaterial-like printed spiral coils (PSCs) for improving the proximity effect of metal plates in wireless power transmission. The proposed four-PSC system is experimentally and theoretically verified by power transmission, impedance matching, resonant frequency, magnetic field distribution, and induced eddy current on metal plate. Results demonstrate that the transmission of the four-PSC system is 9.2 dB higher than the conventional two-PSC system when the backside metal plates are added.
