In the field of circularly polarized light (CPL) detection, metasurface-based circular polarizers face a critical trade-off: 3D or multi-layer chiral metasurfaces achieve high polarization extinction ratios (ER) but require complex fabrication processes, while single-layer structures are easy to fabricate but suffer from low ER (usually below 20 in simulations).Single-Layer Chiral Metasurface for Circularly Polarized Light Detection
