Abstract : An exact method is developed for analyzing the electrical performance of a rectangular wave-guide T-junction in which the cross sectional dimensions of the side waveguide are different from the cross sectional dimensions of the through waveguide. The formulas derived for the equivalent admittance matrix of the T-junction are general in that they apply to any right-angle rectangular waveguide T-junction; the side arm of the T-junction may be placed in any position in either the broad or narrow wall of the through waveguide provided that all waveguide surfaces are either at right angles or parallel to each other. This method requires the inversion of an can be obtained by considering a matrix of finite but sufficient size. Numerical calculations for two particular T-junctions showed that accuracies of about one-half percent can be achieved using applied to the analysis of other rectangular waveguide discontinuities or junctions for which no exact analysis is presently available.
