We have extensive expertise in the field of transient analysis and simulation of lossy coupled interconnects. Recently we developed a new technique based on identifying natural modes of oscillation unlike many other transmission-line models which are based on travelling waves. The approach follows directly from previous work for the simulation of a single-phase power coaxial cable. The technique is readily applicable to modelling coupled interconnects and avoids the time-consuming convolution of many existing transmission-line modelling approaches.

The coupled transmission line system for these results is that defined in Fig. 9 of (Kyung Suk Oh 2000). It is depicted in the figure below.

The following figures show the voltage waveforms at the near and far end of the transmission line on both the driving and quiet lines. The transient simulation results are superimposed on the exact frequency-domain results. Accuracy is found to be excellent.
