Super-resolution characteristics of time-reversed electromagnetic wave

时间反演电磁波在特定的远场环境下具有超分辨率特性.结合时间反演技术构建具有超分辨率特性的模型进行仿真,对结果分析后筛选出能够实现超分辨率特性的关键因素,可为实用的小型化、多天线无线通信系统的设计提供指导.

Time-reversed electromagnetic wave has the property of super-resolution in some special far-field circumstances. A model with the property of super-resolution was constructed and simulated by time-reversal technique. By analyzing the simulation results,we can find the main reason for realization of property of super-resolution. The research provides support for the design of compact multi-antenna wireless communication system.
