Embodiment Construction

[0104] As noted above, the present disclosure relates to coupled electromagnetic resonators having long-lived oscillatory resonant modes that can wirelessly transfer power from a power source to a power sink. However, the present technique is not limited to electromagnetic resonators, but is general and can be applied to a variety of resonators and resonance objects. Therefore, we first describe the general technique and then disclose electromagnetic examples for wireless energy transfer.

[0105] resonator

[0106] A resonator can be defined as a system capable of storing energy in at least two different forms, and in which the stored energy oscillates between the two forms. A resonance has a specific mode of oscillation with a resonant (modal) frequency f and a resonant (modal) field. The angular resonance frequency ω can be defined as ω=2πf, the resonance wavelength λ can be defined as λ=c / f, where c is the speed of light, and the resonance period T can be defined as T=1 / ...

Abstract

Described herein are improved configurations for a wireless power transfer for electronic devices that include at least one source magnetic resonator including a capacitively- loaded conducting loop coupled to a power source and configured to generate an oscillating magnetic field and at least one device magnetic resonator, distal from said source resonators, comprising a capacitively-loaded conducting loop configured to convert said oscillating magnetic fields into electrical energy, wherein at least one said resonator has a keep-out zone around the resonator that surrounds the resonator with a layer of non-lossy material.
