AbstractThe evanescent wave re-construction performance in the time reversal system with periodic sub-wavelength grating is studied in this paper. Both the analysis and calculation results show that the evanescent components of the initial wave can’t be re-constructed directly by far field time reversal processing. The results indicate the uncertainty of the super-resolution performance of the time reversal technique with randomly arranged scatters. A new method to achieve super-resolution imaging by using evanescent-to-propagation wave conversion also been proposed at the end of this paper.
