* EZNEC does not know or care about "standing waves" and "traveling
waves". As has been explained many times, the NEC-based simulation tools
simply look at the total current, without making any philosophical value
judgments about the mobility of the waves. It is clear that you have
loaded some sort of conditions into EZNEC that you believe represent
standing waves and traveling waves. However, the argument becomes
completely circular at that point, as you have loaded the conditions
that give exactly the results you desire. If there is a hidden "wave
type" parameter in EZNEC, please let us know. I will humbly retract my
criticism.

You are of course completely right, and I've explained this to Cecil
several times. But he seems to have difficulty with the concept of
current as being simply the rate of charge flow. EZNEC does not, either
in internal calculations or in reporting, split the current into any
kind of "traveling wave", "standing wave", or any other kind of wave
components.
Anyone interested in the details of EZNEC calculations can find them in
the NEC-2 manual which is available on line.
