Dual-Polarization Quasi-BIC Refractive Index Sensing via Dielectric Symmetry Breaking in TiO$_2$-BeS Metasurfaces
A TiO2-BeS metasurface uses dielectric symmetry breaking to produce polarization-selective quasi-BIC and magnetic dipole resonances with reported sensitivities of 243 and 179 nm/RIU in the near-infrared.
