Let me turn the question around, Cecil: can you explain in detail how
any directional coupler gets its directional properties, using *only*
your concepts of power waves?


Sure, P=V*I and V/I=Z0 for both forward waves and reflected waves. The
angle between the voltage and current is always zero degrees or 180 degrees
for any traveling wave. The ratio of voltage to current is always Z0 for
any traveling wave.
