摘要

我们提出了一种系统的方法来合成有利于改善天线辐射方向图的超表面(MS)角滤波器:通过推导反射系数的一种方便的有理函数形式，我们促进了这种器件的高效和灵活的设计。我们通过设计具有严格设计的物理MS内含物的相位可调的全通角滤波器，通过全波模拟验证了我们的框架。我们的结果为从理论到实践完全控制MSs的角响应铺平了道路。

Systematic Design of Metasurface Angular Filters

We present a systematic methodology for synthesizing metasurface (MS) angular filters, which are beneficial for improving antenna radiation patterns: by deriving a convenient rational-function form for the reflection coefficient, we facilitate efficient and flexible design of such devices. We validate our framework via full-wave simulations by devising all-pass angular filters with tunable phase featuring rigorously designed physical MS inclusions. Our results pave the path towards complete control over the angular response of MSs, from theory to practice.
