| Abstract: | The cutoff frequencies of TE and TM 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 Helmholtz's equation is solved by method of moment.Comparisons with numerical results found in the literature validate the presented method. |
