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.
