Optimization of imaging systems containing metasurfaces using a ray-wave model

Résumé

We describe a methodology for optimizing imaging performances of optical imaging systems containing both refractive optical elements and metasurfaces. The modelling of systems is done with a combination of geometrical and Fourier optics to take into account diffraction effects in the computation of the imaging performances. A surrogate model based on the local periodicity approximation is used to calculate the optical response of meta-atoms. System optimization is performed using an evolutionary strategy that takes into account both the distribution of meta-atoms on the metasurface and the geometry of refractive lenses.
