Default Standing morphing to travelling waves, and other stupid notions

I challenged you to post the math, Gene, and you are apparently afraid
to do so. I'll bet you $100 that I am right and can prove it. I showed
that two plane waves in free space form standing waves with the total
E-field either 0 or 180 degrees apart from the H-field, contrary to
what you asserted. Please prove me wrong. If you cannot, please send
me $100.

If you would put aside your delusions of grandeur and simply sketch
those fields on a piece of paper, you would see for yourself that I am
right. When I get back home, I'll knock out a 3D graphic that will
leave no doubt.

Cecil,

This is truly bizarre. The E-field and the H-field are always at right
angles to each other in the plane wave case. They are also perpendicular
to the propagation direction. The same is true for the TEM mode in a
coaxial waveguide, which is the usual case discussed on RRAA. There is
no 0 or 180 degree involvement. I don't know what you are so confused
about, but you really need to rethink what you are saying.

There is no need to sketch or calculate anything. A diagram showing the
relationship of the E-field vector and the H-field vector is in every
E&M and optics book I have ever seen. I presume that Hecht has the same
diagram.
