Design of the dielectric metasurfaces with three different order diffraction modes. a Schematics of lateral dimensions of the 13 designed nanobricks. First line M 1: a supercell with transmitted phase ranging from 0 to 2π. Second line M 3: a rearranged super cell with phase ranging from 0 to 3 × 2π. Third line M 5: a rearranged super cell with phase ranging from 0 to 5 × 2π. b The simulated transmission phases of the 13 designed nanobricks of three different modes under XLP (black lines) and YLP (blue lines) incidences, respectively. c a (black solid lines) and b (black dotted lines) of the 13 nanobricks used in the designed metasurfaces M 1. The blue lines represent the transmitted efficiencies of the 13 nanobricks in M 1 under XLP (solid lines) and YLP (dotted lines) incidences, respectively
