Polarization-insensitive dual-band response governed by quasi bound states in the continuum for high-performance refractive index sensing

Polarization-insensitive dual-band response governed by quasi bound states in the continuum for high-performance refractive index sensing

The introduction of distortions into the metasurfaces with in-plane symmetry offers a possibility to achieve resonances with high quality (Q) factors, but such distortions make the metasurfaces sensitive to the polarization state of the incident light. Here, we propose and numerically demonstrate a...
