Abstract

The regulation of the spatial energy distribution of a light source with high efficiency is a classical and challenging issue in the field of nonimaging optics. In this work we derive the partial differential equation that the metasurface phase function must satisfy to produce a desired illumination pattern by refraction, it is a Monge-Ampére equation, and with the specific boundary conditions, the problem can be solved with a numerical tool.
