Simulation results of a designed metalens with NA = 0.73 at the illumination wavelength of 633 nm. The area of this metalens is 7.5 × 7.5 μm2 (30 × 30 units), and the focal length is 5 μm. (a) Normalized intensity profile of the metalens at the focal plane (z = 5 μm). (b) Corresponding normalized intensity profile along the red dashed line in (a). Normalized intensity distribution in the x-z plane (c) and y-z plane (d). The metalens is designed at λd and the focal length of the metalens is designed to be 5 μm
