Schematic of the proposed metasurface for achieving complete CVF control. The proposed single‐layer dielectric metasurface can achieve independent and simultaneous control over the amplitudes and phases of the LCP and RCP transmitted waves based on spin‐decoupled interference effect. By designing the superposition of the field distributions of the transmitted LCP and RCP components, the amplitude, phase, and polarization of the overall transmitted field can be arbitrarily controlled.
