Abstract
Various aspects of the subject technology include a wireless power transmission design based on extended range near-field resonance coupling induction, where magnetic near-field range may be extended by several orders of magnitude. One element that may help to accomplish the near-field extension, in one aspect, is the addition of a transformational magnetic lens to the transmitter. The magnetic lens may be made of metamaterials with refractive index of for example, −1. It may recover and collimate the near-field evanescent, magnetic flux, effectively extending the near-field coupling distance by several orders of magnitude.
