The argument starts at page 30 of one book , and at page 4 of the other book , continuing on page 5. Here in figure 9.2 we see “a very narrow pulse introduced at the front end of the active line. If there were no parallel passive line nearby, this pulse would travel down the active line (at the speed of light for the dielectric) more or less unchanged,” in a TEM mode. “However, as the other two traces show, the presence of the passive line caused the original narrow pulse to break up into two similar pulses.”

I failed to realise the key message from this paper for 46 years (not 43, because publication was blocked for three years). I was too excited by discovering the two velocities, which were not known, and missed the main chance, which is discussed here , in 2010, after 46 years
