摘要
该文采用多模网络与严格模匹配相结合的方法分析了介质周期结构在电磁波斜入射情况下的散射特性。定量地分析了这种三维频率选择表面结构的频率选择特性随入射波的频率、入射角度、周期层和均匀层的厚度与介电常数等结构参数的变化关系,从而为三维介质频率选择表面的设计和应用提供了依据。
In this paper the scattering characteristics of dielectric periodic structures by an oblique incidence are analyzed by a method which combines the multimode network approach with rigorous mode matching method. The dependence of frequency selective characteristics of the 3-D frequency selective surface(FSS) structures on frequency and angle of the incident wave and the structure parameters is quantitatively studied. Therefore, some guidelines for design and application of the 3-D FSS structures are given.
