Abstract

A distinguishing feature of high-index dielectric nanoparticles is their ability to support strong Mie resonances, thereby enhancing the interaction of light with matter and minimizing Ohmic losses, leading to unprecedented efficiency. An important advancement in this field is the investigation of the "transverse Kerker" effect, in which both forward and backward scattering are significantly reduced while lateral scattering is enhanced. We uncover that the realization of a perfect transverse Kerker effect is possible even in passive structures, by exploiting the physics of bound states in the continuum—electromagnetic states remaining localized in photonic structures, coexisting with outgoing waves. Such 'transverse Kerker BICs' are polarization independent, and in momentum space are pinned at the center of polarization vortices with high order topological charges.
