Abstract
Embodiments of the invention disclose a system configured to exchange energy wirelessly. The system includes a structure configured to exchange the energy wirelessly via a coupling of evanescent waves, wherein the structure is electromagnetic (EM) and non-radiative, and wherein the structure generates an EM near-field in response to receiving the energy; and a negative index material (NIM) arranged within the EM near-field such that the coupling is enhanced.
