摘要

提出了在时间反演技术条件下单频的电磁波信号可以实现超分辨力聚焦这一思路，并基于信道理论推导了该思路的可行性；基于传统的同轴探针结构建立了间距为1/4波长的微结构模型，仿真结果证实了该模型结合时间反演技术在单频信号和宽带信号激励时均可以表现出超分辨力聚焦特性. 理论分析和仿真结果为单频以及多频带天线的超分辨力聚焦特性的研究提供了重要的指导作用.

关键词:

The idea that single-frequency electromagnetically excited signal can possess the property of super-resolution focusing under time reversal technique is proposed in this paper. The feasibility of the idea is investigated from the channel theory. A micro-structured model with inter-element spacing of 1/4 wavelength is proposed based on the traditional coaxial probe antenna. Simulated results verify that in combination with time reversal technique, the model shows super-resolution focusing characteristics under single-frequency and broadband input signal excitation. The theoretical analysis and simulated results have great guiding significance for the super-resolution research of the single-frequency and multi-band antennas.
