Well, it would be easier if you didn't delete the
context. I assume you are talking about the energy
components associated with the canceled waves, traveling
rearward before the cancellation and traveling forward
after the cancellation where the cancellation is a
continuous process (until source power is turned off).

In s-parameter terms, the two joules/sec components are
(s11*a1)^2 and (s12*a2)^2 when b1^2=0 as explained in the
HP Ap Note.

In ham terms, they are Pfor1(rho^2) and Pref2(1-rho^2)
where Pfor1 is the forward-traveling source power incident
upon the impedance discontinuity and Pref2 is the rearward-
traveling reflected power incident upon the impedance
discontinuity from the other direction.

Note that I am using common usage terms for "forward power"
and "reflected power" since their units are watts. I would
normally talk about "forward energy" and "reflected energy"
to avoid the wrath of the purists. :-)

In terms of my article, they are P3 and P4 whe

P3 = Pfor1(rho^2) and P4 = Pref2(1-rho^2)

Pref1 = P3 + P4 - 2*Sqrt(P3*P4) = 0
