Quarter-Wave Plate Meta-Atom Metasurfaces for Continuous Longitudinal Polarization Modulation of Hybrid Poincaré Sphere Beams

Quarter-Wave Plate Meta-Atom Metasurfaces for Continuous Longitudinal Polarization Modulation of Hybrid Poincaré Sphere Beams

Quarter-wave plate (QWP) metasurfaces provide a novel approach for generating three-dimensional (3D) hybrid-order Poincaré sphere (HyOPS) beams and enabling longitudinal polarization modulation, owing to their unique spin-decoupling properties. In this work, we designed a set of QWP meta-atom metasu...
