Abstract

eficial for low-loss metamaterials. The planar scheme of manipulating the coupling among the ASRRs may stimulate research in optical regions involving toroidal multipoles. The toroidal geometry together with the Fano resonance of ASRR-induced high-Q response will have enormous potential applications in enhancing light-matter interactions, e. g., for low-threshold lasing, low-power nonlinear processing, and sensitive biosensing.
