On the physics and design of plasmonic anapoles in metallic nanostructures

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...

More Information
Summary: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.
