| 摘 要： | 本文对双对对称双脊波导进行了系统的分析,根据对称性分区求解了 Helmholtz 方程.将TR 波分为四类模式,得出了每类模式在各区中解的形式,从物理上得出了这种波导中模式问题的清楚解释,由分界面上的匹配条件导出了矩阵方程.本文计算得出的基模及高次模的截止频率和场分布从物理意义上均能很好地吻合.

| Abstract: | The systematic analyses of the waveguide with two pairs of double ridges are carried out in this paper.According to the symmetry of the waveguide,by solving the Helmhotz equation in different regions and dividing TE modes into four kinds of modes,we obtain the solutions of every kinds of modes.So the physical meaning of the mode problem is explained clearly.By matching in the boundaries or the different regions and using the Ritz's functions and the method of inner products,we derive the matrix equations of one kind of modes.In the calculated conclusions,the cut-off frequencies and distributions of fields of dominant and high modes coincide with the physical meaning very well. |
