2 circ. pol. fields at 90 degrees

[Mark Roberts]

Can someone with a better grasp of vector dynamics than myself please
tell me what occurs interactively when two identical circularly
polarized EM fields meet at right angles?

Do they cancel or transform in some predeterminable way?

Thank you,

Mark Roberts

Well, EM fields are linear = superposition. Add it up and see.

Making little circles in the air with my fingers, I'm going to guess the
result is another wave equal to the linear combination of the two starting
waves. And maybe multiplied by their relative phase (which varies in space,
as the wave is supposed to, so maybe it disappears into the description of
the result).

Odd newsgroup to ask about EM waves though... hell, we don't even design
antennas here...
