摘　　要：给出扇面波导ＴＥ模式场分量的近似表达式，根据等效原理，应用矩量法（Ｇａｌｅｒｋｉｎ法）求解了扇面波导宽面窄横缝口面电场的分布，研究了散射参数、归一化等效串联阻抗、谐振电阻、谐振长度等重要参数．The exact and approximate expressions for the field components of the TE modes in a sectoral waveguide are given.Using the equivalence principle,the electric field distribution on the aperture surfaces of a narrow transverse slot cut in the curved broad wall of a sectoral waveguide is solved by the moment method (Galerkin′s method).Important results such as the scattering parameter,the normalized equivalent series impedance,the resonant resistance and resonant length are studied.
