Arrangement positions (a) and corresponding rotation angles θ1 (b) when VO2 is metallic and codes “1”, “2”, “3”, “4” represent VO2 meta-atoms. Simulated far-field holograms as well as grayscale maps and their target maps are demonstrated under LCP incidence (c), RCP incidence (d), and LP incidence (e). Positions (f) and rotation angles θ2 (g) of gold patches as VO2 is insulating. Holograms and grayscale maps are exhibited for LCP wave (h), RCP wave (i), and LP wave (j).
