Since its introduction by Nikola Tesla in 1900, the concept of wireless power transmission has expanded in many directions, including high-intensity microwave beams, lasers and mutual magnetic induction. Far-field systems such as lasers, focused microwaves and large aperture RF links are well suited for traversing large (>100 m) distances but exhibit relatively low (<10%) overall system efficiencies due to beam diffraction limits, atmospheric absorption and multiple conversion losses. Near…
