Abstract
The invention relates to a device that can be used to transfer power wirelessly, which is based on at least two resonators comprising photonic crystals defined by multiple layers of two different materials disposed concentrically and producing a circular sandwich-type structure. In one of the preferred embodiments of the device of the invention, the photonic crystals of each resonator of the device are disposed concentrically, which is the preferred configuration for each resonator, although different configurations can be used in alternative embodiments in which the photonic crystals are disposed radially. The outside radius of each resonator can be defined according to various parameters, with the parameter referring to the wavelength of the working frequency being one of the preferred parameters when establishing the outside radius.
