Reg, how about these statements from a recent QEX article?

"Contrary to popular views, the forward and reverse
waves on a transmission line are not separate fields."
"I wish to emphasize the fact that the forward and
reverse waves really do not exist separately, ..."
"Dual Directional Wattmeters", Eric von Valtier, K8LV,
_QEX_, May/June 2006.

The article obviously rejects the wave reflection model
for transmission lines as presented by Ramo/Whinnery,
Johnson, etc.

If forward and reverse waves do not exist separately,
how is it possible for a circulator to separate them?
