• time reverse
• super-resolution
• sub-wavelength structure

Time-reversed system with a sub-wavelength structure is one of the necessary conditions for the system to show spatial super-resolution characteristics. In the near field zone, Coulomb field predominates the transmission of signals. The resolution limit of Coulomb field is characterized only by the sizes and the spatial distribution of scatterers, which is useful for obtaining the super-resolution beyond the diffraction limit.
