【摘要】 本文提出一种聚焦窄带时间反演无线输能方案,能够降低时间反演操作的实现难度,可望实现高能效、低危害、多目标的无线能量传输。在密闭的金属混响腔内,经过电磁仿真和实验验证,具有16个输能天线的聚焦输能系统可以达到87%的无线链路效率,即使将输能天线的数量缩减至2只,链路效率也可以达到40%以上。更多还原

【Abstract】 A narrow-band time reversal(TR) method is proposed for focusing wireless power transmission(FWPT). The scheme can reduce the difficulty of TR implementation, and it is expected to achieve wireless powering with high efficiency, multiple targets and low electromagnetic harm. The simulations proved that the spatial efficiency of the FWPT system with 16 transmitting antennas can reach 87% inside a metal reverberation chamber. Experimentally, the system can obtain more than 40% spatial efficiency when only 2 transmitting antennas are adopted.更多还原
