Analytical Solutions of the Scattering Properties of H-Plane Junctions in Rectangular Waveguides.

The scattering properties of the H-plane waveguide discontinuities such as the cross junction, T-junction, and right-angle, and are analyzed taking their symmetry into accounts. The solutions are synthesized in two new and simple expressions. These solutions are tinted rigorously by the mode-matching method in which each junction section is divided by a circular region and the electromagnetic fields are matched with the scattered waves into waveguide regions at the boundaries. By means of the accurate numerical results obtained in a wide frequency range, the scattering properties of the H-plane junctions in a standard waveguide and an oversized waveguide an examined in detail. The Latter is believed to be useful for an approximate estimation of the scattering properties of crossing roads in underground shopping centers. [ABSTRACT FROM AUTHOR]
