Time reversal electromagnetics is a new branch of science. The critical factor for the practical implementation of time reversal technique is to obtain time reversed signal efficiently. In this paper, based on the principle of time lens, a method of obtaining time-reversed microwave signal is studied. First, according to the principle of time lens, conditions for realizing time-reversed waveform are derived. The process for obtaining time reversed signals is simulated numerically. Then two chirp electromagnetic bang gap (CEBG) structures are fabricated to construct dispersion channels. And a time reversed signal on a 1.5 ns time scale is obtained in experiment. Due to the difference between CEBG and ideal dispersion channel, there exists a distortion in the experiment results, for whitch the reasons are analyzed.
