摘　　要：提出一种使用保角变换结合矩量法,计算复杂形状波导截止频率的新方法,该方法采用解析法或数值法,把复杂截面的波导变换为圆形区域,再采用矩量法求解波导的截止频率。实验结果验证了该方法的有效性。The cutoff frequencies of TE and TIM model in uniform waveguides with an irregular cross section are computed via a combination of the method of moment and the conformal mapping. A conformal mapping is applied to transforms the waveguides section onto the circle. And the Helmhohz＇s equation is solved by method of moment. Comparisons with numerical results found in the literature validate the presented method.
