a Schematic of proposed meta-deflector. b Theoretical and simulated phase profiles of meta-atoms located along x-axis to provide required phase gradients in all four CP transmission channels. c Simulated and measured normalized far-field patterns for channels L–L, L–R, R–L, and R–R at 10 GHz, respectively. d Photograph of fabricated sample of proposed meta-deflector. e Measured normalized far-field intensities against frequency bandwidth (9–11 GHz) and detection angles for channels L–L, L–R, R–L, and R–R, respectively.
