Quasi-Bound State in the Continuum-Driven Co-Frequency Polarization-Multiplexed Tunable Terahertz All Dielectric Metasurface
Quasi-bound states in the continuum (q-BICs) provide an effective approach for achieving strongly confined resonances in metasurfaces. However, the simultaneous realization of high-Q, polarization-multiplexed, and tunable resonances at a single frequency using a single resonant meta-atom remains challenging. Here, we n...
