Principle of the virtual shaping based on spin-orbit conversion in space-variant half-wave plates.
(a), Schematic of the scattering from a planar surface with space-variant phase distribution under circularly polarized illumination. (b), The phase shift Φ for a rotated half-wave plate under illumination of a circularly polarized wave. (c), The scattered waves from an axicon under normal incidence. (d), Scattering of axicon at normal incidence in the k-space.
