This work employs a new approach to analyze coupled-resonator circuits to design and manufacture a fully metallic dual polarization frequency selective surface (FSS). The proposed filtering structure is composed of a series of unit cells with resonators fundamentally coupled along the z-direction and then repeated periodically in the xy-plane. The fully metallic cascaded unit cell is rigorously analyzed within an infinite periodic environment as a coupled-resonator electromagnetic (EM) circuit. The convenient design of the EM resonators makes it possible to push the evanescent EM field through the metallic structure in the desired frequency band for both polarizations. An FSS prototype is manufactured and measured, and good agreement is found between the simulation results and the final prototype.

本研究采用一种新颖的方法，用于分析耦合谐振电路，以设计和制造全金属双极化频率选择表面（FSS）。所提出的滤波结构由一系列单元单元组成，这些单元单元沿z方向基本耦合，并在xy平面中周期性重复。全金属级联单元细胞在无限周期环境中被严格分析，作为一个耦合谐振电磁（EM）电路。电磁谐振器设计的便利性使得能够将指数衰减的电磁场在期望的频率范围内推过金属结构，以实现两种极化方式。一个FSS原型已制造并进行了测量，仿真结果与最终原型之间表现出良好的一致性。
