Abstract
A wireless power transfer apparatus for providing wireless power; it has an array of resonators; a powered resonator for providing power through electromagnetic resonance to said array of resonators; wherein said resonators transfer power from said powered resonator to any one of said array of resonators for delivering wireless power to said device by a modified connection between said array of resonators except the powered resonator; and/or wireless weak electromagnetic field coupling between neighboring resonators of said array of resonators each having a tuning frequency of resonance wherein said array of resonators has at least two distinct tuning frequencies from all the resonators constituting said array of resonators; wherein said modified connection is one of or a combination of: a wired connection; and a strong electromagnetic field coupling.
