提对称双脊波导脊的大小变化改变其传输特性参数，采用亥姆霍兹方程有限元方法计算出双脊波导主模截止波长数值，结果与文献结果对比说明计算方法精确有效，求对应的特征向量，就可得到脊波导横截面上的电场分布，从而分析脊大小变化对场结构图的影响。

The transfer characteristic parameter of Double -ridge waveguide can be changed by mutative ridge .The influence of the mutative ridge on the field pattern of the dominant mode in a double -ridge waveguide is analyzed by the finite -element method .Numerical results demonstrated that the method is correct and efficient .The proper vector is calculating by characteristic value ,and the field pattern is easy obtained .So we can analysis the field pattern with mutative ridge of Double -ridge waveguide .
