Аннотация: Non-radiating sources have attracted researchers’ attention in wave scattering on dielectric nanoparticles in nanophotonics. Wireless power transfer systems suffer from low efficiency due to the ohmic and radiation loss of the resonators included in the transmitter and receiver. In this paper, we develop a non-radiating wireless power transfer system implemented by non-radiating sources as its transmitter and receiver. The non-radiating source consists of an ultra-high permittivity dielectric disk resonator and a small metal loop antenna. We demonstrate that the non-radiating behavior arises from destructive interferences of the waves radiated from different parts of the source. We experimentally study the efficiency of the wireless power transfer system and demonstrate high power transfer efficiency due to the radiation loss suppression. © 2022 IEEE.
