The square meta-atom employed for the multi-bit coding scattering reduction metasurface with multihyperuniform disorder. (a) The square patches are made of copper (σ = 5.8×10⁷ S/m) with varying sidelength w for the different species, the FR-4 substrate's height is h =1 mm with ε_r= 4.6 and tan δ = 0.001, the periodicity of the unit cell is p =7.5 mm and the patches are backed by a PEC plane. (b) Simulated reflection phase results for varying w for the five different species. (c) Simulated reflection amplitude for varying w for the five different species.
