Symmetrical six-port waveguide junction with metallic post and dielectric sleeve in over-sized cavity

Abstract

The Least-Squares Boundary Residual Method is employed in the present paper to develop a computer model of the sym-metrical six-port wave guide junction. The analytical formulation is difficult because of the insertion of a metallic post together with a dielectric sleeve into the over-sized cavity of the junction. Computational and experimental tests confirm that the resultant model is able to compute the scattering parameters of such a structurally-complicated component with numerical accuracies of ±0.001 and ±0.1° for magnitude and phase respectively.
