Abstract

In this paper a segmentation technique, based on hybrid (admittance and impedance) matrix representations, is proposed for the efficient and accurate analysis of rectangular waveguide multi-port junctions with arbitrarily shaped waveguide access ports. The technique is completely outlined, and a new method for solving the connection of hybrid matrices without intermediate inversions is derived. To validate the theory, results for a magic-T junction and a six-port cross junction are compared with experimental data from literature. The new method proposed is also successfully applied to H- and E-plane T-junctions with rounded corners in the side arms.

Résumé

Dans cet article on propose une technique de segmentation basée sur des représentations matricielles hybrides (impédance et admitance) pour ľanalyse efficace et exacte de jonctions multi-port de guides ľondes rectangulaires aux ports de forme arbitraire. La technique est expliqée en détail et ľon en déduit une nouvelle méthode pour résoudre la connection de matrices hybrides sans inversions intermédiaires. Pour valider la théorie, on compare les résultats obtenus avec une jonction T-magique et avec une jonction à six ports avec des données expérimentales de la littérature. La nouvelle méthode proposée est aussi employée avec succès pour résoudre des jonctions T des plans E et H ayant des coins arrondis dans les bras latéraux.
