The space-time coding metasurface. a The illustration of the space-time coding metasurface. (from Fig. 1 of Ref. [77]). b and c The space-time coding pattern for beam-deflection. (from Fig. 4 of Ref. [77]). d The calculated scattering pattern of the configuration in b and c. (from Fig. 4 of Ref. [77]). e The designed equivalent pattern for a 3-bit modulation. (from Fig. 2 of Ref. [77]). f and g The equivalent pattern and scattering pattern for an OAM beam. (from Fig. 4 of Ref. [77]). Reproduced with permission from Ref.
