Analysis of rectangular waveguide discontinuities by the method of lines

An efficient analysis of discontinuities in the rectangular waveguide is presented using the method of lines with one-dimensional discretization. As the line numbers in the incoming and outgoing waveguides are automatically correctly chosen in the method of lines, relative convergence is avoided. Scattering parameters for the E-plane step discontinuity are determined and an equivalent circuit for the diaphragm, the displacement, and a step with diaphragm is presented.<
