Modeling of centimeter-scale metasurfaces in imaging systems

Description

In recent years, metasurfaces have emerged as promising components for reducing the size and complexity ofoptical imaging systems. Nevertheless, their incorporation into these systems remains a challenge due to thedifference between the numerical tools used in the design of conventional imaging systems (ray tracing) and thedesign of metasurfaces (full-wave solvers). In this paper, we describe a methodology that combines the localperiodicity approximation and a free space propagation technique to rapidly compute the optical response of alarge-scale metasurface. We then explain the coupling of this fast solver with a ray tracer to accurately simulatean optical system containing a metasurface.
