摘要

我们考虑具有工程反射和透射系数的互易超表面，并研究法向(相对于超表面平面)电极化和磁极化对形成反射和透射响应的可能性的作用。我们在一般和代表性的例子中证明，偏振矢量的法向分量的存在不会在工程上增加超表面的反射和透射特性的额外自由度。此外，我们还讨论了功能元表面相同性质的等效体积实现和全平面实现的优缺点。

Functional metasurfaces: Do we need normal polarizations?

We consider reciprocal metasurfaces with engineered reflection and transmission coefficients and study the role of normal (with respect to the metasurface plane) electric and magnetic polarizations on the possibilities to shape the reflection and transmission responses. We demonstrate in general and on a representative example that the presence of normal components of the polarization vectors does not add extra degrees of freedom in engineering the reflection and transmission characteristics of metasurfaces. Furthermore, we discuss advantages and disadvantages of equivalent volumetric and fully planar realizations of the same properties of functional metasurfaces.
