High-quality-factor Fano resonance and tunable light absorption based on diagonal circles of the bound state in the continuum

High-quality-factor Fano resonance and tunable light absorption based on diagonal circles of the bound state in the continuum

This study proposes a novel metasurface structure made of dielectric diagonal round holes. It is possible to achieve the quasi-bound state in the continuum (quasi-BIC) resonance modes with high Q-factors by introducing symmetry breaking into the unit structure. The quality factor and line width can...
