Absurd. Current does not "get radiated".


It's *energy* in the traveling wave that gets radiated.
Less energy indeed lowers the current amplitude.


Agreed. But when discussing current, one should recognize that, with
the exception of "non-flowing current" whatever that is, all currents
produce a field. Field cancellation is what prevents the transfer of
energy. Any of this sounding familiar to you? The standing wave
pattern is useful for illustrating what the field interference pattern
might look like.

w7el "measured" the phase shift in current
that doesn't flow.


:-) He's good, but he ain't that good. Besides, his meter is the same
as yours in that it only responds to waves that travel and currents that
flow. The difference I suspect, is in the desired outcome and the
rhetoric.

I've said my piece.
