Permittivity-asymmetric chiral metasurfaces empowered by bound states in the continuum

Permittivity-asymmetric chiral metasurfaces empowered by bound states in the continuum

The intrinsic chirality of natural materials is usually weak or absent. To enlarge circular dichroism, chiral metasurfaces supporting bound states in the continuum have been widely investigated. These chiral metasurfaces have demonstrated considerable potential to achieve high quality (Q) factors bu...
