摘要
本文用模匹配法分析了任意角度平面波入射时分析一般单元缝隙阵频率选择表面（ＦＳＳ）的频率响应特性．这里考虑的ＦＳＳ是一零厚度无限大平面阵．问题的解是以Ｆｌｏｑｕｅｔ定理为基础，通过匹配ＦＳＳ表面的切向场分量获得的．它适用于单屏和结构完全对称的双屏ＦＳＳ，并且考虑了多层介质衬底的影响．文中以“十”字环形缝隙阵单屏ＦＳＳ为例，详细分析了布阵方式、单元尺寸、介质衬底、入射角以及极化等对其频率响应特性的影响．
By using modal matching, frequency response of frequency selective surfaces (FSS) with apertures is studied for zero thickness and infinite planar conducting sheet. The excitation is assumed to be a plane wave incident at any arbitrary angle. Based on Floquet theory,the solution is obtained by matching the tangential field components at the surface of the screen. Both single and double-FSS configurations are studied and the effects of multilayered dielectric substrate are taken into account. Then,the typical results of the influence of the lattice,element configurations and incidence angle on the performance of FSS consisting of arrays of cross-loop slots are summarized.
