摘要

基于周期金属线阵的等效电介质模型, 并使用传输线理论方法, 得到了金属线阵中时间反演电磁波的解析表达式. 接着, 在等效电介质模型的适用范围内, 讨论了金属线半径、金属线阵周期、金属线阵周期数对时间反演电磁波聚焦的影响. 从而在理论上证实, 这种结构可以实现远场时间反演电磁波聚焦, 同时, 也为时间反演技术提供了工程参考.

关键词:

Based on the equivalent dielectric model of the periodic metal wire array, the analytical expression of time reversal EM wave in the metal wire array is derived using transmission line method. Then, the influence of metal wire radius, metal wire array period and the amount of layers on time reversal EM wave focusing property is discussed within the equivalent dielectric model. This structure can be used to focus time reversal EM wave in the far field, at the same time, it provides an engineering reference for time reversal technique.
