We demonstrate the ability to transfer 60W with approximately 40% 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%. We discuss practical applicability and suggest directions for further studies.在强耦合状态下使用自谐振线圈，我们实验证明高达线圈半径的八倍的有效的非辐射功率传输。 我们展示了在距离超过两米的情况下以大约40％的效率传输60W的能力。 我们提出一个描述电力传输的定量模型，将实验结果与5％以内相匹配。 讨论实际适用性，并提出进一步研究的方向。In the early 20th century, before the electrical-wire grid, Nikola Tesla (1) devoted much effort towards schemes to transport power wirelessly. However, typical embodiments (e.g. Tesla coils) involved undesirably large electric fields. During the past decade, society has witnessed a dramatic surge of use of autonomous electronic devices (laptops, cell- phones, robots, PDAs, etc.) As a consequence, interest in wireless power has re-emerged (2–4). Radiative transfer (5), while perfectly suitable for transferring information, poses a number of difficultie
