From: Design of Phase Gradient Coding Metasurfaces for Broadband Wave Modulating
Geometry of optimization layout and the far field RCS simulated by MLFMA at X band in dB scale. (a) The size of the metasurfaces is 150 mm × 150 mm and the OF is θ1 = θ2 = θ3 = 45°, φ1 = 90°, φ2 = 210° and φ3 = 330° for three lobes of radiation. The simulation of the metasurface at X band are conducted at: (b) 8 GHz; (c) 9 GHz; (d) 10 GHz; (e) 11 GHz; (f) 12 GHz. (g) The RCS of three lobes versus the frequency.
