Extrinsic Limitations of Stealthy Hyperuniform Devices

ABSTRACT Hyperuniformity promises an unusual form of wave control: the suppression of elastic scattering over extended angular ranges without periodic order. Here, we present a comprehensive experimental and theoretical study of 2D stealthy hyperuniform metasurfaces operating at...

Real-space spin-orbit interaction from quarter-wave plate nonuniformity

Abstract Spin–orbit interactions couple light polarization to its transverse structure. Although widely studied at interfaces, in tilted anisotropic plates, and under tight focusing, their role in paraxial confocal systems remains unclear. We show that a commercial quarter-wave p...
