Wireless Energy Transfer Using Arrays of Resonant Objects
First Claim
1. A system for exchanging energy wirelessly, comprising:
- an array of at least three objects, wherein the objects have similar resonant frequencies, wherein each object is electromagnetic (EM) and non-radiative and generates an EM near-field in response to receiving the energy, wherein each object is electrically isolated from the other objects and arranged at a distance from all other objects, such that upon receiving the energy, the object is strongly coupled to at least one other object via a resonant coupling of evanescent waves; and
an energy driver for providing the energy at the resonant frequency to at least one object in the array, such that, during an operation of the system, the energy is distributed from the at least one object to all other objects in the array via the resonant coupling of the evanescent waves.

Abstract
A system for exchanging energy wirelessly includes an array of at least three objects, wherein the objects have similar resonant frequencies, wherein each object is electromagnetic (EM) and non-radiative and generates an EM near-field in response to receiving the energy. Each object is electrically isolated from the other objects and arranged at a distance from all other objects, such that upon receiving the energy, the object is strongly coupled to at least one other object via a resonant coupling of evanescent waves. An energy driver provides the energy at the resonant frequency to at least one object in the array, such that, during an operation of the system, the energy is distributed from the at least one object to all other objects in the array via the resonant coupling of the evanescent waves.
