Experimental Characterization of Partially Degenerate Three-Conductor Transmission Lines in the Time Domain

In a recent paper [1], a method for the time-domain characterization of lossless multiconductor transmission lines with cross sectionally inhomogeneous dielectrics was presented. This method is limited to lines with completely nondegenerate propagation; i.e., all the modes have distinct propagation velocities. In this paper, a method is presented for the characterization of lossless partially degenerate three-conductor lines, together with experimental data. The results are in good agreement with independent frequency-domain measurements.
