Novel design method of frequency selective surface

提出一种小单元尺寸频率选择表面的设计方法。该方法基于多面互耦合原理对结构进行传输线等效,根据等效模型可对小型选择表面的传输特性进行较精确的计算。利用提出的等效模型方法,建立结构与模型的参数化关联,可由给定的传输特性输入条件直接计算结构参数,简化了设计过程。

This paper proposed a novel method to design the structure of FSS which based on the principle of polyhedral mutual coupling. The equivalent model can be obtained through the theory, thus, we can calculate the characteristics of the FSS according to the model. The relationship between the structure of FSS and the parameters of the equivalent model with the method. Then, we can calculate the parameters of the structure directly with the given characteristics of the FSS.
