On the concept of a generalized law of refraction: A phenomenological model The Article and the Supporting Informations
摘要：
本文研究了由衍射元件构成的超颖表面的广义折射和反射定律。它引入了一个唯象模型，再现了致力于广义斯内尔-笛卡尔定律的实验的所有特征。我们的主要发现是，为了描述光通过由衍射元件制成的超颖表面的传播，必须修改如前所述的广义折射和反射定律。我们提供了适当的法律，采取不同的形式取决于属性的元表面。我们的模型适用于周期性和非周期性的元表面。我们表明，广义折射定律严格存在的线性相位配置文件和锯齿波相位配置文件的约束下，我们指定的。它可以近似地定义为非线性相位分布。本文件包括第一部分的文章和第二部分的支持信息。
英文摘要：
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.
