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.
