Comments on "Simulation of lossless symmetrical three conductor systems" by W. Guggenbuhl et al

W. Guggenbuhl et al. (see ibid., vol.10, pp.904-910, 1991) presented an example of modeling a three-conductor interconnection system and simulating the transients with the use of the SPICE program. The commenters point out that Guggenbuhl did not reference some important publications in the area and leaves an impression that the problem of simulation of multiple, coupled, lossless transmission lines has not yet been solved. These comments are intended to rectify this situation and to inform interested readers about the actual status of this problem and recent relevant publications.<>
