摘要
根据扇面波导中主模的近似简化场分量表达式，推导出特性阻抗的三种形式，波导壁导体损耗，最大功率容量，截止波长近似式；并利用功率平衡关系推导出波导宽边横缝的等效谐振串联电阻的简法近似公式，给出计算实例。
Three expressions of the characteristic impedances,the attenuation constant due to conductor losses and the maximum power handling capability are derived from the approximately simplified field components of the dominant mode in a sectorial waveguide. The approximate formu-la of the cutoff wavelength for the transverse electric modes are given,and the normalized resonant serial resistance for the narrow transverse slot cut in the curved broad wall of the waveguide is also presented.The examples are given.
