Here are a number of problems. I(f) is forward current and
I(r) is reflected current. Please everybody, perform the
following phasor additions where I(f)+I(r) is the *standing
wave current*:

I(f) I(r) I(f)+I(r)

1 amp at 0 deg 1 amp at 0 deg 2 A @ 0 deg

1 amp at -30 deg 1 amp at +30 deg 1.72 A @ 0 deg

If you guys will take pen to paper and fill in those blanks
you will uncover the misconception that has haunted this
newsgroup for many weeks. If you need help with the math,
feel free to ask for help.

What misconception? That all current in a standing wave has the same
phase, rather than one of two possible phases?
