Ultrathin Pancharatnam-Berry Metasurface with Maximal Cross-Polarization Efficiency
Recent years witnessed a surge of interest in metasurfaces providing phase-discontinuities, which find novel applications in flat lenses, spin-orbit manipulation, wavefront engineering, information processing, and holography, to name a few. Compared to conventional lenses or imaging devices, metasurfaces provide an alternative approach to wave control and manipulation, thickness reduction, pixel refinement, and transverse resolution.
