TLDR
In this paper, an apparatus for use in wireless energy transfer is described, which includes a first resonator structure configured for energy transfer with a second resonance structure over a distance D larger than characteristic sizes of the first and second resonator structures.Abstract:
Disclosed is an apparatus for use in wireless energy transfer, which includes a first resonator structure configured for energy transfer with a second resonator structure over a distance D larger than characteristic sizes, [insert formula] and [insert formula], of the first and second resonator structures. A power generator is coupled to the first structure and configured to drive the first resonator structure or the second resonator structure at an angular frequency away from the resonance angular frequencies and shifted towards a frequency corresponding to an odd normal mode for the resonator structures to reduce radiation from the resonator structures by destructive far-field interference.read more
