DIELECTRIC NANO-PHOTONICS-III: THE DISCOVERY OF ELECTRODYNAMIC ANAPOLES IN SILICON NANODISKS
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.
