The paper presents a numerical simulation of the propagation characteristics of symmetric E-type and H-type waves in microwave circular shielded waveguide with radially inhomogeneous dielectric filling. Using the modified Galerkin method, the calculation of a circular two-layer shielded waveguide was carried out, as a result of which the distribution of the electromagnetic field of the waveguide with linear and parabolic distribution of permeability was determined. The results obtained using the modified Galerkin method were compared with the results obtained using the classical partial domain method, which agree well enough.

径向非均匀介质填充微波圆形屏蔽波导中对称波传播特性的数值模拟

本文对径向不均匀介质填充的微波圆形屏蔽波导中对称E型和H型波的传播特性进行了数值模拟。采用改进的Galerkin方法，进行了圆形两层屏蔽波导的计算，从而确定了具有线性和抛物线磁导率分布的波导电磁场分布。将使用改进的 Galerkin 方法获得的结果与使用经典部分域方法获得的结果进行了比较，两者非常吻合。
