That's not the point at all. The question is pretty
simple. Does the principle of superposition give us
permission to analyze the individual forward and
reflected waves separately and then superpose the
results? If you say "no", then you don't accept the
superposition principle. If you say "yes", then
please stop harping that the only valid way to solve
a problem is your way.

Just forget about ExB (or more commonly, ExH).

Your advice is to forget acquired knowledge and tools
and put one's trust in who? You?

Cecil,

I have said many times that you can choose to analyze the individual components or you can analyze the superposed combination, i.e., a standing wave. It is purely a matter of mathematical convenience. However, if you get different answers, including more or less completeness, then you have made an error. That is the essence of superposition. If that property was not true, then superposition would be of little value.

It is rather ironic that you are accusing *me* of allowing only one valid method when I have repeatedly stated a flexible approach. Is that some sort of debating technique you learned?

Are you instead seeing a reflection of yourself? Is this some sort of mirror trick?
