Abstract:

Mode matching method is used to analyze the scattering characteristics of the circular-to-circular groove waveguide junction. Matching the electric fields and magnetic fields at the boundary of the junction, and multiplying the mode functions of the circular waveguide and circular groove waveguide on both sides of the boundary equation, the scattering matrix equation is obtained, the scattering coefficients can be obtained from the equation. Then the scattering characteristics of the iris with circular window in circular groove waveguide are analyzed. At last the convergent problem is discussed; when choosing a suitable mode group, convergent numerical results are obtained, and the frequency response of the iris’ scattering coefficients is also given.
