a The reflection efficiency and b the phase of the periodic regular hexagonal nanorods for different values of w in the wavelength range of 1000–1800 nm. c Scattering cross section \(Q_s\) versus the wavelength of an isolated regular hexagonal silicon nanorod. The contribution of each term to the Mie expansion is shown. d Phase profiles obtained via eigenmode analysis and numerical simulations for varying side length w. e Schematic of the designed phase-gradient metasurface
