摘要
用直线法对一维非均匀矩形波导进行了分析 ,由传递矩阵获得了该波导不同模式的特征方程。以部分非均匀介质填充的矩形波导为例 ,对其色散特性和截止特性进行了数值计算和分析 ,验证了该方法的正确性。对研究非均匀波导问题有参考价值。
The rectangular guide filled with One-dimensional inhomogeneous dielectric is analyzed by using the method of lines in this paper, and the characteristic equations of different mode of the guide are obtained by using transfer matrixes. Taking the rectangular guide partially filled with inhomogeneous dielectric as an example, the dispersion and cut-off characteristics are numerically calculated and analyzed, and accuracy of the method is verified. It is of some reference value for studying inhomogeneous guide.
