The currents are referenced to the source. When the forward
current and reflected current are in phase at zero degrees,
they are at a maximum and flowing toward the load so their sum,
the net current, is flowing toward the load. 1/2 cycle later,
the forward current and reflected current are in phase at
180 degrees so their sum, the net current, is flowing toward
the source.

Hi Cecil,
Actually, net current doesn't flow at all in a standing wave. Current is
the rate of change of charge, dQ/dt. In a standing wave, the rate stays put.
The charge may be vibrating wildly at a point, but the average rate
of change (or even the peak, if that's what's important to you) doesn't move.
If it does move, the wave is a traveling wave, not a standing wave.
If you were right, then the rate of change of charge would alternately
move into and out of your miraculous coil. In other words, there would be
an oscillating traveling wave moving first one way and then another, into and
out of the coil, and it would do so at both ends, as in some particularly
lurid,
x-rated movie.
This is what happens when you don't understand the math, Cecil. You
make stupid mistakes based on a faulty understanding of the fundamentals.
I hate to be a fundamentalist like your minister, but I'm sure beginning to
appreciate his approach.
