Polarization-Robust and Electrically Tunable Quasi-Bound States in the Continuum in C4-Symmetric Terahertz Metasurfaces for Refractive-Index Sensing
Polarization sensitivity and limited tunability remain important challenges for high-Q terahertz (THz) metasurfaces based on quasi-bound states in the continuum (q-BICs), particularly when geometric perturbations are introduced to enable radiative coupling. Here, we numerically demonstrate a graphene-integrated all-die...
