Metalens Phase-Profile Designer

Design a polarization-insensitive transmissive metalens: generate the radial phase map, suggest nanopillar pitch, and predict the focal-plane MTF.

Design flat metalenses using Kriya HRI NIL resins. Compute the hyperbolic phase profile, check Nyquist pitch constraints, predict Strehl ratio, and visualise the modulation transfer function. Includes nanopillar diameter library for phase discretisation.
