A Method for Calculating Eigenmodes of Shielded Waveguides with a Complex Smoothly Varying Shape of the Cross Section

摘要

A method is proposed that can be used for calculating eigenmodes of shielded waveguides with an arbitrary smooth dependence of the waveguide parameters on the transverse coordinate. A system of differential equations with boundary conditions is obtained to which the solution of the problem can be reduced. The method is tested with the use of the example of homogeneously and partly filled shielded waveguides. The efficiency of the method is demonstrated through comparison with known results.
