Thank you very much for sharing this. I've been trying to form a mental model of why reflection in transmission lines is a thing and never found a theoretical foundation that satisfied me. I've read a number of publications that just state that as fact, without further explanation. I'll spend some time sketching my own graphs and formulas to fully absorb the fine article.
PS: he discusses the impossibility of moving signals faster than light. I'm in fact interested in moving them way slower than they do, since that could make it possible to build very short antennas. I'm surely not the first to think of this. Maybe that's not even possible and that theoretical model could help to demonstrate why (even though it applies to transmission lines while I'm concerned about antennas).
