It is exactly that kind of misleading terminology that has caused his
text to fall out of favor among many physics faculty.

:-) Please argue with Hecht if he is still alive or with
his ghost if he is not.

You really aren't qualified to speak on behalf of the field of optics,
Cecil.

Oh yes, instead of anything technical, we get an argumentum
ad verecundiam from you, the delusionary diversion gurus use
when they are sure they already know everything. Jim, it is
obvious that you don't even understand the intensity equations
in Born and Wolf. Wade through the S-Parameter analysis that
I have started and I will prove it to you.
