Bill,
I agree with you for the real case. But to say by definition there can't be
swr - I think that would only be the case with infinitely small source and
loads and zero spacing between.
So that for whatever conductor and distance there does exist between the
ultimate current sources and sinks "point zero", there would exhibit the
standing wave due to the mismatch. Even the anode, in a sense, has a
distributed conductor shape. Pretty smeared over the geometry involved -
but it's got to be there.
I did not get a chance to nit pick on the skin effect discussion and so
wanted to get in something usless on this one. hi hi
