High-Q Resonances Induced by Toroidal Dipole Bound States in the Continuum in Terahertz Metasurfaces

The radiation mode of the interaction between electromagnetic waves and materials has always been a research hotspot in nanophotonics, and bound states in the continuum (BICs) belong to one of the nonradiative modes. Owing to their high-quality factor characteristics, BICs are extensively employed i...
