A numerical approach for the solution of the scattering by an inhomogeneous H-plane discontinuity of arbitrary shape in a rectangular waveguide is described. The approach is a combination of the finite-element method and the analytical method. The validity of the method is confirmed by comparing numerical results for a waveguide-type dielectric filter, a right-angle corner bend, an inductive strip-planar circuit mounted in a waveguide, a T-junction and an inhomogeneous waveguide junction with the earlier theoretical and experimental results.
