Huygens metasurface supporting quasi-bound states in the continuum for terahertz gas sensing

Jose Antonio Álvarez-Sanchis, Borja Vidal, Ana Díaz-Rubio

We investigate a terahertz (THz) gas sensing platform based on all-dielectric metasurfaces that support quasi-bound states in the continuum (quasi-BIC) with both electric and magne…
