Metasurface Simplified Model for Lens Design Applications

We propose a workflow to introduce metasurfaces in optical design by using semi-analytical models. These models recover the output phase and polarization after propagation through the metasurface and can be used within optical design software. As such, metasurfaces can be optimized in optical systems by using built-in optimization processes while avoiding time-consuming electrodynamics computation. We present three variations of a triplet composed of a metasurface and refractive elements, all with similar optical performances.
