Abstract

Nanostructures with anapole states have attracted significant interest in the field of nanophotonics due to their ability to exhibit field enhancement while providing transparency, specifically a low extinction cross-section [1, 2]. Anapoles have been observed in both dielectric [3] and plasmonic [4] nanostructures. Typically, anapole states arise from the interference between electric and toroidal dipole moments. However, even in cases where the toroidal dipole contribution is negligible due to a planar design, the presence of an anapole can still be observed.
