摘　　要：本文采用散射矩阵级联的方法，分析了多层周期性金属栅条构成的圆极化器的极化性能。每一层栅条关于Ｆｌｏｑｕｅｔ模的散射矩阵由采用全域基函数的Ｇａｌｅｒｋｉｎ方法求得。圆极化轴比和驻波比的本文计算值与实验值吻合较好，证实了本文分析方法的有效性。A strip-type circular polarizer consisting of multi-planar periodic surfaces is investigated by combination of scattering parameters of each periodic surface. The scattering parameter of every surface is analyzed by the Galerkin method in spectral domain and the entire domain basis functions are selected. The calculated VSWR and axis ratio of the circular polarizer agree quite well with the experimental results. Thus,the effectiveness of the analysis is verified.
