SIMPLE AND ACCURATE SOLUTIONS OF THE SCATTERING COEFFICIENTS OF E-PLANE JUNCTIONS IN RECTANGULAR WAVE-GUIDES

Simple and accurate solution of the scattering coefficients of the E-p lane right-angle bend in rectangular waveguide is presented. The solut ion is obtained by the mode-matching method in which the electromagnet ic fields in waveguides are matched with those in junction section for med by a sectoral region. In the same procedure, the solutions of the scattering coefficients of the E-plane T-junction and the cross juncti on can be also obtained easily. By using the numerical results, the sc attering properties of the dominant modes and higher-order modes in th e E-plane right-angle bend are examined in detail.
