Symmetry-Breaking-Induced Quasi-Bound States in the Continuum in All-Dielectric Terahertz Metasurface for High-Sensitivity Refractive Index Sensing and Theoretical Virus Differentiation
Bound states in the continuum (BIC) have recently attracted extensive research interest, owing to their exceptional capability for light confinement and high quality-factor (Q-factor) resonances. In this work, we design an all-dielectric terahertz metasurface based on the symmetry-breaking properties of silicon rectang...
