摘要
以圆环单元为基础提出了一种新型的频率选择表面(FSS)结构单元，即在圆环单元内部设置一偶极子单元，运用谱域Galerkin 方法对这种单元结构的传输特性进行了数值分析。结果表明该新单元结构在平面电磁波30°和45°倾斜入射的情况下，横电波(TE 波)、横磁波(TM 波)在11.5 GHz 的透射比较高，而在14 GHz 附近，TE、TM 波的透射特性完全相反，实现了极化分离的特点。
Abstract
Based on the ring loop element, a new element which sets a dipole slot in the ring loop element is introduced. The new combining element frequency selective surface (FSS) structure is calculated Galerkin's method in the spectral domain. The transmittance of both transverse electric wave (TE wave) and transverse magnetic wave (TM wave) at skew angle incidence of 30° and 45° is high at about 11.5 GHz. But it also exhibits polarization splitter at about 14 GHz.
