Asymmetric Orthogonal Metasurfaces Governed by Toroidal Dipole Bound States in the Continuum

An all-dielectric metasurface composed of orthogonal-slit silicon disks is proposed in this study. By modifying the unit structure of the metasurface with the bound states in the continuum (BICs), a sharp Fano resonance can be generated. The resonance properties of the metasurface are investigated b...
