Abstract

Resonant optical excitation of high index dielectric nanoparticles offers unique opportunities for reduced dissipative losses and large resonant enhancement of both electric and magnetic near-fields. In this regard, there is a ‘new kid on the block’, namely electrodynamic ‘anapole’ mode (i.e. ‘without poles’ in Greek. In this talk, I will discuss how high-index dielectric nanostructures under resonant excitation of the anapole mode can act as a non-radiating/radiationless source, which can confine energy efficiently by minimizing radiative loss.
