System for transferring energy wirelessly
First Claim
1. System for transferring energy wirelessly comprising:
- a housing including a plurality of housing walls defining a space, at least a wall of said housing configured to be placed adjacent to an electromagnetic energy reception device,an oscillator configured to generate an electrical signal, andan injector configured to receive the electrical signal supplied by said oscillator, and configured to inject electromagnetic waves into said space,wherein a cutoff frequency and a cutoff wavelength are associated with said housing,whereinsaid walls are electrically conducting walls,a frequency of the electromagnetic waves is lower than said cutoff frequency, andsaid wall comprises at least one aperture,wherein said at least one aperture has a size smaller than a wavelength of the electromagnetic waves so that an evanescent electromagnetic field is emitted from said at least one aperture.

Abstract
There is disclosed a system for transferring energy wirelessly by an evanescent electromagnetic field. The system includes a housing including electrically conducting walls defining a space and an injector configured to inject electromagnetic waves into the space. A wall of the housing is configured to be placed adjacent to an electromagnetic energy reception device and includes one or more apertures. The frequency of the electromagnetic waves is lower than the cutoff frequency of the housing, and the one or more apertures have a size smaller than the waves wavelength so that an evanescent electromagnetic field is emitted from the one or more apertures of the wall and may reach the energy reception device.
