Abstract

Recently, several new principles for wireless power transfer have been demonstrated overcoming the limitations of the conventional wireless power transfer systems. In this work, we investigate a metasurface-enabled bound states in the continuum for near-field wireless power transfer. The metasurface is made of complimentary split-ring resonators in which a symmetry-protected bound state in the continuum is formed. We show that a wireless power transfer channel emerges between the metasurface and a single complimentary split-ring resonator element effectively increasing the transferred power by 15 dB compared to the case without the single element.
