With an existing metal wire array structure, this paper verifies the temporal and spatial focusing properties of the time reversal techniques, and confirms the super-resolution focusing properties of the time reversal electromagnetic waves. Since the metal wire array can provide an evanescent-wave channel, by changing the signal incentives to the time reversal mirror (TRM), this paper achieves some satisfactory simulation results of subwavelength off-site imaging. The analysis and simulation results indicate that with time reversal technique, we can use traditional materials and equipment to achieve super-resolution confocal imaging in the far field, and extract and analyze the source signal at different positions.
