EZNEC deals only with total currents and makes no effort to detect, use,
or break up total current into individual traveling waves.

Then, without effort, EZNEC accurately reports the presence
of traveling waves or standing waves as can be seen from
the graph of the EZNEC results at:

The graph on the left is for traveling wave current. Its
magnitude is fixed and its phase varies with wire length.
Traveling wave phase can be used to determine the phase
shift through the wire (or through a coil).

The graph on the right is for standing wave current. Its
phase is fixed and its magnitude varies with wire length.
Standing wave magnitude can be used to determine the phase
shift through the wire (or through a coil) by taking the
arc-cosine of the magnitude.
