摘要

研究了亚波长聚焦近场阵列与功率传输效率最大化阵列之间的关系。对电容负载环形阵列的磁场进行分析，结果表明，以最优功率传输效率为目标设计的电容负载环形阵列的磁场集中可以使功率传输效率最大化，这一直观的预期并没有得到证实。概述了损失的重要作用，并说明了基础物理的有趣方面。

Magnetic near-field focusing and optimal wireless power transfer

The relation between subwavelength focusing near-field arrays and arrays designed to maximize power transfer efficiency is investigated. The intuitive expectation that magnetic field focusing around the receiver may maximize power transfer efficiency is not confirmed, when the fields of capacitively loaded loop arrays, designed for optimal power transfer efficiency, are analyzed. The significant role of loss is outlined and interesting aspects of the underlying physics are illustrated.
