Mode matching analysis of metallic plates in radial waveguide

Mode matching method is a useful way to analyze the mode characteristics during the section change of the waveguide. By applying this method to the radial waveguide and solving specific problems due to the radial transmission of electromagnetic wave, a calculating method in radial waveguide based on mode matching is presented. The scattering characteristic of metallic plates in radial waveguide is calculated, and the calculated result is proved qualitatively by simulation, which indicates the validity of this method.
