Polarization-Selective Holographic Metasurface For Creating Cylindrical Vector Beams

Generalized cylindrical vector beams (GCVB) are spatially polarization inhomogeneous. It could be considered as a combination of a radially polarized beam and an azimuthally polarized beam with different weighting factors. Here, we report a holographic metasurface patterned on a gold film layer for generating a GCVB. The nanostructure is a superposition of an individually oriented nanoslit array t...
