衍射界面理论:超颖表面光学的非局部极化率方法

Diffractive Interface Theory: Nonlocal polarizability approach to the optics of metasurfaces

Christopher M. Roberts, Sandeep Inampudi, Viktor A. Podolskiy

摘要:

我们提出了一种理解电磁超颖表面,光学薄膜与工程衍射复合膜的形式主义。该技术,衍射界面理论(DIT),明确利用超颖表面的小光学厚度,消除了对解决薄膜内部的光传播的需要,并提供了超颖表面的空间轮廓和其衍射特性之间的直接联系。DIT的预测进行了比较与麦克斯韦方程组的全波数值解,证明DIT的有效性和计算的光学薄结构的优势。DIT的应用范围从理解超颖表面中光-物质相互作用的基本原理到有效分析广义折射到超颖表面优化。

英文摘要:

We present a formalism for understanding the elecromagnetism of metasurfaces, optically thin composite films with engineered diffraction. The technique, diffractive interface theory (DIT), takes explicit advantage of the small optical thickness of a metasurface, eliminating the need for solving for light propagation inside the film and providing a direct link between the spatial profile of a metasurface and its diffractive properties. Predictions of DIT are compared with full-wave numerical solutions of Maxwell's equations, demonstrating DIT's validity and computational advantages for optically thin structures. Applications of the DIT range from understanding of fundamentals of light-matter interaction in metasurfaces to efficient analysis of generalized refraction to metasurface optimization.
