Abstract

We show toroidal dipole resonances excited by symmetry-breaking nanocylinders in the near-infrared band. Excitations of the electromagnetic resonances by detailed multipole decompositions and near-field distributions are discussed and subsequent experiments also supported the theoretical predictions.
