A fully automated solution for designing metalens/metasurface systems has been developed to optimize the parameter values of each meta-atom on each metasurface based on the given inputs and desired targets. Unlike traditional design approaches, which are based on a given phase profile for a particular incident condition, inverse design can generate the optimum layout and its simulation results automatically based on a limited set of inputs from designers. The knowledge required of designers is minimized significantly. Hence, designers at different levels of expertise, including undergraduate students, can use this software solution to design metalens systems quickly.
