For the record:

____X____ Standing wave current magnitude contains NO phase

Remember the context is the 1/2WL thin-wire dipole fed
by 1 amp at 0 degrees on page 464 in Kraus' "Antennas
For All Applications", 3rd Edition where the standing wave
current magnitude EQUALS cos(X) where X is the number of
degrees away from the feedpoint. The arc-cosine of the standing
wave current magnitude *IS* the phase.

One other point. At least one expert has said that nothing
is lost in the superposition process. We know that the
forward traveling wave has phase and the reverse traveling
wave has phase. If the superposed standing wave current
magnitude contains no phase information, then something was
lost in the superposition process because the standing wave
current phase certainly contains no phase information as
illustrated at:
