Reflection and refraction problems for metasurfaces related to Monge-Ampère equations
Cristian E. Gutierrez, Luca Pallucchini
A metasurface is a surface, tipically a plane, on which a function called phase discontinuity is chosen so that the metasurface produces a desired reflection or refraction job. We…

General Refraction Problems with Phase Discontinuity
Cristian E. Gutierrez, Luca Pallucchini, Eric Stachura
This paper provides a mathematical approach to study metasurfaces in non flat geometries. Analytical conditions between the curvature of the surface and the set of refracted direct…
