And if recent history is any indicator, half the posts would be from
you, contributing virtually nothing to the discussion.

That's what I've been saying. Make sure you remember and apply that
concept when you're talking about 'direction'.

All I've talked about, Jim, is the direction of current flow. The bottom
line for you is, EZNEC doesn't display a real-time plot of antenna current
as you first thought. An antenna's current changes phase every 1/2 cycle.
EZNEC's current display is referenced to the source current at zero degrees
and nowhere else.

Right. But some of the things you've been saying about it are
incorrect.
I've been pointing them out in this thread.

??? I've never even expressed an opinion about EZNEC.

Hint: In a standing wave ratio, there is still the flow of
coulombs, but it's more like they are sloshing back and forth (AC)
between the high voltage nodes.

And here's a hint for you: Assume two phase-locked lasers are pointed
at each other. Such a configuration will exhibit standing waves where
all the energy is contained in the electric field at some points and
1/2WL away, all the energy is contained in the magnetic field.

Do you really expect anyone to believe that given two interfering beams
of light, that the combined energies in those two light beams "are sloshing
back and forth" between the points where the net electric field equals
zero. Pray tell, what physical phenomenon is causing all those reflections?

Hint: Your assertion has been proven wrong by numerous experiments with lasers.
It is no more true for transmission lines than it is for lasers. The two beams
of light are "transparent" to each other just as forward current is transparent
to reflected current. The coherent waves traveling in opposite directions have
absolutely no effect on each other until they encounter a common discontinuity.

You forget the entertainment factor - there is nothing in this thread
beyond the first three posts that have elevated this beyond
vaudeville. Glad to see you trying to wrest the percentage tho'

Actually, that's your logic, Richard. The math model dictates reality
and therefore, the balls will never hit the ground. I, OTOH, have a
better grasp of reality than to believe math models dictate reality.

Exactly how lasers work.

Exactly where they work.

They are called "mirrors." And they are set at the Brewster Angle.
It is impossible to remove them from the system if both beams are
boresight aligned.

You are observing the result of the destructive or constructive
interference. The standing wave, is still an abstraction used to define it.

We can't even get folks to agree whether current flows from positive to
negative, or negative to positive. and guess what, it doesn't matter.

The whole thing is just a figment that allows us to explain phenomena in a
rational manner. That is until the Clintonistas among us want to argue the
meaning of what is IS.

90% of the bandwidth in this forum is used by this kind of nonsense. While
it serves the ego of the proponents of their pet theory, it does nothing to
impart knowledge to the group.

I am sure, if I met Cecil in person, I would really enjoy being around him.
His hobby on the internet is debate, he creates the premise, and offers up
information that is designed to encourage a person to take a direction
already determined by Cecil. He then sets back and plays semantics games
untill you lose the debate by frustration.

With a tip of the hat to "WHOPPER" -"The only way to win, is not to play the
game..."

Standing waves are in fact the observable result of the superposition of
traveling waves. Interferometers are devices which function because of
the fact that standing wave interference patterns are observable. Radio
interferometers allow us to do radio astronomy with improved spacial
resolution. We most certainly can see standing waves.
