Results of the multifunctional metasurface. a Configuration of the plate with graphene reflectarray consisting of 36×36 graphene patches. The widths (wy) of all graphene patch are taken as 4 µm, and values of wx are selected to realize the phase discontinuity condition as shown in Fig. 6. b The magnitude of the electric field of the reflected vortex wave of l=1. The incident wave is an x-polarized electromagnetic wave with normalized electric field, impinging normally from the top. The wave is deflected by 30 towards x-direction
