Abstract
Metasurfaces for controlling wavefronts are typically designed for plane-wave illumination from a specific direction. However, the behaviour of these metasurfaces for arbitrary illuminations has not been analyzed so far. In this presentation, we study the angular response of anomalous reflectors for arbitrary illumination angles. We will compare the angular response of anomalous reflectors designed with different design strategies. In particular, we explain the dependence of the scattered power for arbitrary illumination angles in phase-gradient metasurfaces, strongly nonlocal metasurfaces, and power flow-conformal meta-surfaces. This study will allow us to complete understanding of the scattering properties of anomalous reflectors and to discern the way to engineer their angular response.Description
