Abstract

We uncover a superscattering behavior of a pseudospin-1 wave from weak scatterers in the subwavelength regime where the scatterer size is much smaller than the wavelength. The phenomenon manifests itself as unusually strong scattering characterized by extraordinarily large values of the cross section even for arbitrarily weak scatterer strength. We establish analytically and numerically that the physical origin of superscattering is revival resonances, for which the conventional Born theory breaks down. The phenomenon can be experimentally tested using synthetic photonic systems.
