Merging toroidal dipole bound states in the continuum without up-down symmetry in Lieb lattice metasurfaces
The significance of bound states in the continuum (BICs) lies in their potential for theoretically infinite quality factors. However, their actual quality factors are limited by imperfections in fabrication, which lead to coupling with the radiation continuum. In this study, we present a novel appro...
