Roy is absolutely right, Cecil. Interact is a very poor choice of
terms in this discussion.

Roy did NOT say "interact" was a poor choice of terms.

That's correct. I said that interact is a poor choice of terms.

He
chose to use it as did Hecht. Hecht says waves interact.
Roy says they don't interact.

As I said, Roy is correct.

Would you assert that photons can have an
effect on each other?

Of course. Coherent photons emitted from different phased
antenna elements obviously have an effect on each other.

That is incorrect. Charged particles and photons interact in antennas.

I have thought long, hard, and deep about it. Wave cancellation
is prima facie evidence that coherent waves can have a permanent
effect on each other, even in free space. I don't know anything
more permanent than wave cancellation bringing both the net
E-field and the net H-field to zero.

And the funny thing is, you say that even you know of instances in
which the net fields are zero, and yet the waves propagate beyond that
point. You've at least seen a picture of an interference pattern,
right?

If you would wade through
the S-Parameter analysis with me, you would understand.

I think you just like to argue.

How about taking the S-Parameter analysis step by step? Then
you can point out the very step where I wander astray of the
laws of physics.

If the S parameter analysis addressed where you are going wrong, then
that might be worthwhile. The problem as I said is with your idea
about waves and energy. Obviously we all get the same answer at the
end of the problem.
