Query: Superscattering Empowered by Bound States in the Continuum   We uncover a novel mechanism for superscattering of subwavelength resonators
closely associated with the physics of bound states in the continuum. We
demonstrate that superscattering occurs as a consequence of constructive
interference driven by the Friedrich-Wintgen mechanism, and it may exceed the
currently established limits for the cross-section of a single open scattering
channel, within the channel itself. We develop a non-Hermitian model to
describe interfering resonances of quasi-normal modes to show that this effect
can only occur for scatterers violating the spherical symmetry, and therefore
it cannot be predicted with the classical Mie solutions. Our results reveal
unusual physics of non-Hermitian systems having important implications for
functional metadevices.
