Experimental demonstration of superdirectivity and superscattering phenomena is among the long-standing challenges in electromagnetic theory. Efficient computational algorithms can contribute to this endeavor by suggesting new designs bypassing commonly accepted limitations. Here, we demonstrate a rectangular wire bundle superscatterer designed using a stochastic optimization algorithm. The structure encompassing wires of different lengths demonstrates superior scattering capabilities, bypassing the single channel dipole limit by an order of magnitude. The subwavelength wire bundle supports several resonant higher-order multipoles, which constructively contribute to the scattering, as we demonstrate experimentally. A new generation of genetically designed superscatterers may be used in a range of wireless applications, including point-to-point communications, smart beacons, and radar targets.
