Summary of the chiral metasurfaces in broadband, weak resonance, and BIC resonance regime. In all those bandwidth regimes, different types of optical chiral responses including 3D intrinsic chirality, 3D extrinsic chirality, 2D intrinsic chirality, and 2D extrinsic chirality are thoroughly discussed29,39,54,67,78,79,88,104,115,155.
