Anapole mode excitation in novel perforated all-dielectric metamaterials

Abstract

In this paper, we concern on nonradiating properties of novel silicon metamaterials due to multipolar interaction. Destructive interference of electric dipole moment and the next term of multipolar decomposition - toroidal dipole moment, leads to nonradiating anapole mode, which is nowadays widely studying among electrodynamic phenomena. Therefore, we propose technically simple metamaterial design, which does not demand multistep fabrication. This kind of metamaterial is the promising in nanophotonics and plasmonics due to subtle sensing, nonradiative data transfer, Aharonov-Bohm effect and other demonstrations.
