Numerical simulation results of 1-bit and 3-bit diffusion coding metasurfaces. (a) 3D scattering pattern of the 1-bit coding metasurface at 1.1 THz. (b) E-plane scattering pattern of the 1-bit coding metasurface at 1.1 THz. (c) E-plane scattering pattern of a bare metal plate with the same dimensions at 1.1 THz. (d) 3D scattering pattern of the 3-bit coding metasurface at 1 THz. (e) E-plane scattering pattern of the 3-bit coding metasurface at 1 THz. (f) E-plane scattering pattern of a bare metal plate with the same dimensions at 1 THz. (g) Simulated backward scattering coefficients of the 1- and 3-bit coding metasurfaces in the frequency range from 0.8 to 2 THz under normal incidence.
