What about Ramo and Whinnery's forward Poynting vector and reflected
Poynting vector? Why do you choose to ignore them?
I haven't used them because I don't need them to arrive at an answer.
Yes, but you need them to arrive at the correct answer. :-)
Basic electricity, a dash of circuit theory, a bit of knowledge of
trigonometry, some basic calculus and the ability to think is all
that is required.
Apparently, that is not all that is required. Here's a neat web page
that will allow you to visualize what is happening. Note the forward
and reflected waves do not change energy or momentum at a zero
voltage point.
