Abstract : The subject of this work is a class of transmission line two-ports. More specifically the two-ports studied are constructed from lossless equal length coaxial lines whose shields are all connected to the common ground terminal. A two-port of this type having n internal junctions and further constrained not to contain a shorted line connected to any of these junctions is referred to as an n-th order strictly coaxial two-port. It is shown that the transition from such a network to its two-port admittance matrix can be represented as an orthogonal transformation effected by an n-th order orthogonal matrix U. This leads to realizability conditions which are formulated in terms of the poles and residues of the two-port admittance matrix and U. In the second phase of the work, two successive subdivisions of the strictly coaxial networks into smaller and more restricted classes are considered and the general results established are applied to them. The class defined by the second subdivision is found to be synthesizable. (Author)
