Tailoring Polarization Conversion in Achiral All-Dielectric Metasurfaces by Using Quasi-Bound States in the Continuum
Quasi-bound states in the continuum (quasi-BICs) supported in all-dielectric metasurfaces (MTS) are known for their confinement in real space and the notably high values of the quality factor Q.Recently, the properties of quasi-BICs have been employed to achieve polarization conversion with all-dielectric MTS.However, one of the main disadvantages
