Generalized analysis of a coaxial waveguide to radial waveguide junction

A new mathematical model of a coaxial waveguide to radial waveguide junction is presented. The solution has been obtained in terms of generalized scattering matrices. At first, closed form expressions for elements of a generalized admittance matrix of the junction have been derived. Then, the generalized admittance matrix has been converted to a generalized scattering matrix.
