Large-angle reflector metasurface. (a) Numerical simulations of the angular reflection in far field for a single supercell of the large-angle reflector. (b) Schematic of the supercell. (c) SEM top view of the fabricated metasurface; the orange dashed box indicates a single supercell. (d) Angular reflection on resonance (λ = 625 nm). The red data indicate the diffracted scattering, and the blue data are specular reflection. (e) Total reflection (black) and scattering without specular reflection (red) of the large-angle reflector.
