Simulation of multichannel waveguide power dividers (Kharkov, Ukraine, September 15-17, 1998)

Three types of microwave waveguide multichannel power dividers based on H-plane hybrid junctions, E-plane T-joint and H-plane launcher on higher waveguide modes are represented in the work. Mathematically exact investigation of such devices has been done by means of the system of electrodynamic simulation, which consisted of decomposing of boundary problems on a set of elementary discontinuites of irregular waveguide. These were: angle bend, half-infinity bifurcation in H-plane and the same discontinuities in E-plane. The diffraction problems of H modes of the above elements have been solved by assuming the metal surface to be an ideal conductor. Multimode S-matrix of bifurcation and step were calculated by the method of moments. Noncoordinate problem of waveguide bend was solved by the semi-inversion method. Recomposition of original structures was carried out by the method of S-matrix
