Plasmonic toroidal response at optical frequencies
Plasmonic toroidal response at optical frequencies
The toroidal spectral responses of integrating four gold U-shaped split-ring resonators (SRRs) at optical frequencies are numerically studied. Based on the distribution of the near-field patterns of the plasmonic resonances, we obtain toroidal and magnetic resonances concentrated by magnetic dipoles around the SRRs at free space wavelength 660 nm and 952 nm, respectively.

Abstract
The toroidal spectral responses of integrating four gold U-shaped split-ring resonators (SRRs) at optical frequencies are numerically studied. Based on the distribution of the near-field patterns of the plasmonic resonances, we obtain toroidal and magnetic resonances concentrated by magnetic dipoles around the SRRs at free space wavelength 660 nm and 952 nm, respectively.
