提出了一种用于无线电力传输的具有均匀磁场分布的空间结构谐振线圈。所提出的谐振线圈的特性通过理论分析、仿真结果和实验测量得到验证。由于均匀的磁场分布，无论接收线圈在传输距离的位置如何，与传统线圈相比，发射和接收谐振线圈之间的整体传输效率可提高高达44%。
A spatially structured resonant coil with uniform magnetic field distribution for wireless power transfer is presented. The characteristics of the proposed resonant coil are verified by the theoretical analysis, simulation results, and experimental measurements. Due to the uniform magnetic field distribution, the overall transfer efficiency between the transmitting and receiving resonant coils can be improved up to 44% compared to the conventional coil regardless of the location of the receiving coil at the transfer distance.
