Abstract
Official abstract text for this publication.
Described herein are embodiments of a source high-Q resonator, optionally coupled to an energy source, a second high-Q resonator, optionally coupled to an energy drain that may be located a distance from the source resonator. A third high-Q resonator, optionally coupled to an energy drain that may be located a distance from the source resonator. The source resonator and at least one of the second resonator and third resonator may be coupled to transfer electromagnetic energy from said source resonator to said at least one of the second resonator and third resonator.
First claim
Opening claim text (preview).
What is claimed is: 1. A wireless power system comprising: a source module comprising a source resonator and a power supply coupled to the source resonator to provide power to the source resonator, the source resonator having a resonant frequency ω 1 , an intrinsic loss rate Γ 1 , and capable of storing electromagnetic energy with an intrinsic quality factor Q 1 =ω 1 /(2Γ 1 ), the source resonator comprising at least one loop of conductive material and further comprising a capacit…
