Yes, forward and reflected power measured at a *FIXED* measurement
point. There is no "power flow" anywhere in my article. Energy
does the flowing. Power is the measurement at a *FIXED* measurement
point of that energy flow past that *FIXED* point. Did you note
the use of the word, "FIXED"?
Even though all my references, including the IEEE Dictionary
allow for "power flow", I avoided it in my article as a favor
to you.
a reference to a supposed "4th mechanism
of reflection" (that's the magical way in which waves of power and
energy change direction),
Yes, that may be somewhat original and therefore frightening
for you. Galileo would have scared you to death. If, as Walter
C. Johnson says, interference can *cause* standing waves, it
can probably also cause reflections at an impedance discontinuity
through wave cancellation. You are going to have to do more
than wave your hands to prove otherwise. Not refusing to
answer my questions about my examples would be a good start.
Remember your absolute refusal to compute the total joules/sec
after the first internal reflection arrived at the thin-film
anti-reflective coating in my example? When you learn how to
properly manage irradiance, get back to us.
and illustrations with arrows named Pref
showing how power is reflected at impedance discontinuities.
No! No! No! Power is NOT reflected at an impedance discontinuity.
Those are Poynting vectors. Energy is reflected and that reflected
energy is measured and called "reflected power". Reflected power
is not moving. You continue to get it wrong. The reflected power
is acutally reflected energy measured flowing past a *FIXED* point
near the impedance discontinuity. There are joules in the reflected
wave. The joules in the reflected wave are measured flowing past
a *FIXED* measurement point. But, of course, I have explained
all of this to you before yet you continue bear false witness
after all these years.
Back when our corresponence was more cordial, I advised you not to write
those things. And now you'd like to deny having done it; all the while
portraying me as a liar. You're beautiful, man.
I changed my article just to make you happy. You obviously
have misunderstood, either through lack of processing power,
ignorance, or deliberately. I would guess it is deliberate.
