Webb6 dec. 2024 · Metasurfaces have recently enacted diverse electromagnetic manipulations in polarization optics. However, they only support one or a few polarization functions in a single design. Here, an arbitrary and dynamic Poincaré sphere polarization converter to implement full-polarization optics with a single time-varying metasurface is demonstrated.
