Haste makes waste, and errors as well. The standing wave power

I'm afraid you will find that those are the equations for
power associated with a traveling wave. Actually should be
Power = V^2/Z0 = I^2*A0. There is no net power transfer
associated with a standing wave. For a pure standing wave,
V*I*cos(A) = 0 watts.
