  • Abstract
    Time reversal electromagnetic waves have time and space focusing properties. So we can use the properties for electromagnetic imaging. Here we report simulations for sub-wavelength focusing using time reversal technique to restore the source image. A kind of metal wire array has been used as an evanescent-wave channel, which could transmit the source image information. We employed time reversal EM waves to restore the source image at the same position and at a determined time.
