| 摘 要： | 根据双层圆环单元FSS周期结构的实验测量经验,应用有限元和周期矩量数值分析方法,建立了单元对准偏差数值分析理论模型。数值分析结果表明,双层圆环单元FSS周期结构的单元对准偏差对其辐射传输和相位特性具有很大影响。对准偏差产生插入相位失真明显,在E0/Dx=50%时,引起插入相位变化约1.33°。

| Abstract: | Since inter layer separation and unit cell aligning errors in double layer frequency selective surface has direct effect on the electromagnetic wave transmission,the unit cell aligning error models were established by using finite element and periodic moment method and according to experimental experience in order to analyze frequency transmission performance for double layer ring unit cell FSS.The data analysis shows that unit cell aligning error causes increase of insert attenuation in the electromagnetic wave transmission and the phase delay.And this error also makes 1.33°insert phase change when E_0/D_x=50%. |
