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.
