Abstract
A wireless power transfer system is disclosed. The system includes a first resonator having a first resonant frequency ω, a half power bandwidth Δω, and an unloaded quality factor Qo=ω/Δωcoupled through a first coupling circuit to a power source, a second resonator having a second resonant frequency ω, a half power bandwidth Δω, and an unloaded quality factor Qo=ω/Δωcoupled through a second coupling circuit to a load, the first resonator disposed a distance away from the second resonator, wherein the distance is smaller than the first and second resonant wavelengths, the first and second coupling circuits are configured so that up to a maximum achievable power transfer efficiency between the first and second resonators can be achieved, wherein Qoand Qocan be less than 100.
