Abstract
Using self-resonant coils in a strongly coupled regime, we experimentally demonstrate efficient non-radiative power transfer over distances of up to eight times the radius of the coils. We use this system to transfer 60W with approximately 45% efficiency over distances in excess of two meters. We present a quantitative model describing the power transfer which matches the experimental results to within 5%, and perform a finite element analysis of the objects used. We finally discuss the robustness of the mechanism proposed and consider safety and interference concerns.
