Default Standing-Wave Current vs Traveling-Wave Current

the REAL answer is that the 'standing' wave is a creation of
experimenters 100 years ago who didn't have the impedance, current, and
voltage measurement tools we have today, and didn't know of or
understand superposition. 'standing' waves are nothing but a result of
superposition of the forward and reflected waves, they have no physical
significance beyond that. it is worthless to talk about power or
energy in them since they can always be broken down into the component
waves which make more sense to work with.

Dave

Whoa!
No physical significance?
Like there is no frying the Hustler loading coil from the bottom up (due
to standing wave current) or corona flames from the tip (due to high SW
voltage) when applying a bit of "worthless" power?

Yuri

not due to 'standing' waves... that is due to the superposition of the
forward and reflected waves. They are the real waves, the 'standing'
ones are just figments of your imagination.

Superposition doesn't work in the environment Yuri described. You've been
hanging around Cecil too long.

ARGH! i was too nice saying that the ancient guys that started the name
'standing' waves didn't understand superposition, neither does everyone in
this group! YES, superposition works in this case, why would it not work???


Evidently, you haven't done enough reading. Yuri is right this time.
