Super-resolution characteristics based on time-reversed single-frequency electromagnetic wave

Abstract : A sub-wavelength three-antenna array that is able to perform super-resolution focusing with single-frequency signal excitations is investigated using time-reversal. The antenna array is loaded with a set of uniformly distributed thin metal wires, which when combined with single-frequency electromagnetic waves from a time-reversal mirror yields a 1=35 wavelength super-resolution focusing at the targeted antenna. The length of the metal wires in particular determines the frequency band enabling super-resolution performance. The results have signi cance for the super-resolution investigation of multi-band compact antenna ar- rays involving micro-structures, with potential linkage with recent studies on super-resolution mechanisms in deterministic complex media.
