Efficient Weakly-Radiative Wireless Energy Transfer: An EIT-Like Approach

Disclosed is a method for transferring energy wirelessly including transferring energy wirelessly from a first resonator structure to an intermediate resonator structure, wherein the coupling rate between the first resonator structure and the intermediate resonator structure is ĸ1 B , transferring energy wirelessly from the intermediate resonator structure to a second resonator structure, wherein the coupling rate between the intermediate resonator structure and the second resonator structure is ĸ B 2 and during the wireless energy transfers, adjusting at least one of the coupling rates ĸ1 B and ĸ B 2 to reduce energy accumulation in the intermediate resonator structure and improve wireless energy transfer from the first resonator structure to the second resonator structure through the intermediate resonator structure.
