 Resonant dielectric metasurfaces have been demonstrated to hold a great promise for manipulating light wave dispersion at the nanoscale due to their resonant photonic environment and high refractive index. However, the efficiency of devices based on dielectric nanostructures is usually limited by the quality, Q, factor of their resonant modes. The physics of the bound states in the continuum, Bix, provide an elegant solution for control over the Q factor of resonant modes. By engineering the substrate of silicon-based metasurfaces, we demonstrate two eigen modes that exhibit an intrinsic magnetic dipole, md, character and have an infinite radiation lifetime. These modes correspond to two groups of Bix, namely Fabroporo Bix and Symmetra Protected Bix. Using temporal coupled mode theory and numerical simulations, we show that these Bix modes can transform into high-Q quasi-Bix resonances with near-unity absorption under normal incidence through tuning structural parameters. Our work provides a promising route to use Bix-inspired metasurfaces for designing ultra-narrowband absorbers which can be used as. This article was authored by Xu Yanzong, Li Xie Li, and Yu Fang Yu.
