Analysis of H-plane discontinuity using Mode Matching Technique
Second International Conference on Innovative Advancement in Engineering and Technology, IAET 2016, National University, Jaipur 1.4.2016
In rectangular waveguides, junction problems can be classified as H-plane problems and E-plane problems. In H-plane problems, the analysis takes place in the plane of the magnetic field of the fundamental mode of the waveguide, whereas in E-plane problem, the analysis takes place in the plane of Electric field of the fundamental mode of the waveguide. A waveguide discontinuity can be analyzed using analytical or using 3-D simulation. Mode matching provides a quick way to analyze these discontinuity problems. The mode matching technique is based on the matching of the total modes at each discontinuity junction between the uniform sections under appropriate boundary conditions. When combined with the generalized scattering matrix technique, this mode matching technique becomes a great method to study many composite waveguide structures. The term generalized implies that both propagating and evanescent modes are taken for the calculation.
