Subwavelength focusing from farfield

Recently, it has been experimentally proved that it is possible to focus beyond the diffraction limit with a far-field Time Reversal. Here, we theoretically, numerically and experimentally investigate the results of this first experiment. We show that a collection of resonant scatterers, placed in the near field of a source, can radiate subwavelength information of this source.
