On the contrary,

"Traveling Wave Engineering", R.K.Moore, page 134:

Fig. 5-12. Voltage and Current Standing Waves on
open-circuited line.

i = Re(V+/Z0)[e^j(wt+bd)+e^j(wt-bd)

This is the same equation for standing wave current
that appears in "Fields and Waves ...", Ramo and
Whinnery.


So I guess that ups the total now to at least two that we know of. Just
exactly how many different kinds of alternating current do you reckon
there are, Cecil? :-)
