径向非均匀圆柱介质波导本征值问题的网络分析

The eigenvalue problem of radially inhomogeneous cylindrical dielectric waveguides is solved by microwave network method. The EM field boundary value problem is represented by equivalent coupled radial transmission line networks, which give clear physical pictrures of the coupling characteristics of the EM fields and the whole calculation procedure is significantly simplified. Numerical examples show that the present method is simple, accurate and versatile.
