基于时间反演电磁波的微结构天线的单频点超分辨力聚焦研究
Research on the single-frequency sup er-resolution fo cusing of micro-structured antenna based on time reversal electromagnetic wave
摘要
Abstract
The idea that single-frequency electromagnetically excited signal can possess the property of super-resolution focus-ing 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.关键词
