All-Dielectric Resonant Metasurfaces with a Strong Toroidal Response

Tuz, Vladimir R.; Khardikov, Vyacheslav V.; Kivshar, Yuri

Description

We demonstrate how to design all-dielectric metasurfaces with a strong axial toroidal response by arranging two types of nanodisks into asymmetric quadrumer clusters. This toroidal response is related to the existence of the trapped (dark) mode that appears due to a symmetry breaking in the cluster. We uncover a correlation between the existence of the toroidal response and asymmetry in the metasurface geometries, which originates from different diameters of nanodisks or notches introduced into...[Show more]
