提出了一种由方形环槽和连接到新颖的独立偏置电路的 PIN 二极管组成的可切换频率选择表面 (FSS)。该结构使用夹在两个物理上独立的金属层之间的非常薄的柔性基板来创建有源滤波器。一个应用是修改建筑物的电磁架构，其中可以使用主动 FSS 控制传播。所使用的元件数量相对较少，形成了紧凑的 FSS 结构，可以安装在建筑物墙壁内的孔中。法布里-珀罗方法用于设计级联版本，以提高滤波器的选择性。
A switchable frequency selective surface (FSS) made of square loop slots and PIN diodes connected to a novel separate biasing circuit is presented. The structure uses a very thin, flexible substrate sandwiched between two physically independent metallic layers to create the active filter. An application is the modification of the EM architecture of buildings, where propagation could be controlled using active FSS. The relatively small number of elements employed creates a compact FSS structure which could fit in an aperture within a wall of a building. The Fabry-Perot approach is used to design a cascaded version for improved filter selectivity.
