摘要

本文利用一种已有的金属丝阵列结构, 验证了时间反演技术的时空聚焦特性, 并证明了在该阵列结构中, 时间反演电磁波具有超分辨率聚焦特性. 利用金属丝阵列能为凋落波提供传播渠道这一特性, 通过改变信号对时间反演镜的激励方式, 得到了多种亚波长异地成像的仿真结果. 本文的分析和仿真结果证实了利用时间反演技术, 可以采用传统的材料和设备, 在远场实现超分辨率聚焦成像, 并能在多个位置实现对源信号的提取和分析.

Abstract

With an existing metal wire array structure, this paper verifies the temporal and spatial focusing properties of the time reversal techniques, and confirms the super-resolution focusing properties of the time reversal electromagnetic waves. Since the metal wire array can provide an evanescent-wave channel, by changing the signal incentives to the time reversal mirror (TRM), this paper achieves some satisfactory simulation results of subwavelength off-site imaging. The analysis and simulation results indicate that with time reversal technique, we can use traditional materials and equipment to achieve super-resolution confocal imaging in the far field, and extract and analyze the source signal at different positions.
