Query: On the concept of a generalized law of refraction: A phenomenological
  model The Article and the Supporting Informations   This paper presents investigations on the generalized laws of refraction and
reflection for metasurfaces made of diffractive elements. It introduces a
phenomenological model that reproduces all the features of the experiments
dedicated to the generalized Snell-Descartes laws. Our main finding is that the
generalized laws of refrac-tion and reflection as previously stated have to be
modified in order to describe the propagation of light through metasurfaces
made of diffractive elements. We provide the appropriate laws that take a
different form depending on the properties of the metasurface. Our models apply
to both periodic and non-periodic metasurfaces. We show that the generalized
law of refraction strictly exists only for linear-phase profiles and
sawtooth-wave phase profiles under constraints that we specify. It can be
approximatively defined for non-linear phase profiles. This document includes
the article as the part I and the supporting informations as the part II.
