Numerical analysis of H-plane waveguide junctions by using densely arrayed electric line currents

This paper presents the scattering property in tapered right-angle corner bend and waveguide T-junction with wedge realized by electric line currents inside the rectangular cavity. The power transmission and reflection coefficients are calculated and presented. These results are compared with the literature and excellent agreements are confirmed. First, the transmission property in right-angle corner bend as a function of normalized frequency is considered. Two analysis models without and with 45deg taper at the corner bend are examined. Secondly, the scattering characteristics in the waveguide T-junctions are calculated. Finally, the transmission and reflection property of the T-junction with wedge realized by using uniform electric line currents is calculated. The validity of this analysis technique using uniform electric current approximation expressed by delta function can be certified. Application of this calculation technique to the other analysis models are a subject for future studies.
