Bottom line: At points '+' in the example before any
cutting, either reflections exist or they don't.

If reflections exist, there has to exist an impedance
discontinuity to cause the reflections. There is no
impedance discontinuity.

If reflections don't exist, there is nothing to change
the direction of the flowing energy. Therefore, energy
is flowing both ways through the '+' points.

Now there's a bit of a pickle. You previously agreed
that
P(x,t) = V(x,t) * I(x,t)
but now you claim that there is energy flowing.

No pickle at all. Any rational person would agree
that if we have 10 joules flowing in one direction
and 10 joules flowing in the other direction that
the *NET* power is zero and the *NET* energy flow
is zero.

When you look at yourself in the mirror, there is
just as much energy flowing toward the mirror as
is flowing away from the mirror yet you see your
image. Do you really think that the EM waves
flowing toward the mirror are interacting with
the EM waves flowing away from the mirror?

But it is easily proven that energy is flowing
from one SGCL to the other.

It would be wonderful if you could provide this
easy PROOF since such a proof would settle the
question.

I already presented the proof. Establish a data
transfer between the signal generator and the
other resistor and then cut the connection. If
you assert that the data connection doesn't
go away, I feel sorry for you.

If the purpose of your argument is to confuse,
confound, and obfuscate, I fully understand why
you are presenting it. If your goal is technical
knowledge, then your approach is pathological.
