All-dielectric double near-perfect absorptions and optical switchings in a permittivity-asymmetric multiple-qBIC-driven metasurface.

We propose a tunable all-dielectric permittivity-asymmetric metasurface capable of supporting dual high-quality (Q) qBIC modes, leading to double near-perfect absorptions (PAs). By breaking the permittivity tensor symmetry through the magneto-optical…
