Abstract

A non-radiative energy transformer is established, which can lead to "strong coupling" between two medium-range distant coils to realize efficient medium-range wireless energy transfer. The distance between the resonators can be larger than the characteristic size of each resonator. Non-radiative energy transfer between the first resonator structure and the second resonator structure is facilitated through the coupling of their resonant-field evanescent tails. Quantitative comparative analysis based on simulation and experiment results has been carried out. Compared with typical magnetic inductive coupling energy transmission devices, the efficiency of the proposed system is much higher.
