✦ Synopsis

This article describes a new fast method that yields an S-parameter's description for a structure immediately after solving the method of moments (MoM) matrix. A virtual elongation is added to the line without extra coupling calculations. The line can be excited by imposing traveling waves with the correct propagation constant and current profile on this elongation. The elongation is also used to modify the line's self-coupling matrix (without changing its size) to make it appear as though it is terminated in a matched load at its fed end. The described method allows a close integration between the method of moments and S-parameter circuit solvers.
