Dual Quasi-Bound States in the Continuum Modes for Optical Activity Manipulation

Quasi-bound states in the continuum (quasi-BIC) are a particular resonant state, which can be regulated by the degree of symmetry breaking in nanostructures. Here, we propose a fourfold rotationally symmetric (C<sub>4v</sub>) metasurface supporting the dual quasi-BIC modes. The Fano char...
