a–c, g–i LCP and d–f, j–l RCP light transmitted through the polarization-dependent metasurfaces in Fourier space. The first row shows results for beam deflection, the middle row for Gaussian-to-vortex beam switching, and the bottom row for topological charge switching. For (c), (f), (i), (l) propagation of the vortex beam through a cylindrical lens was additionally considered.
