Oh, I'm so sorry Cecil, I should have written "However I can not
visualize a simple PHYSICAL mechanism/example to generate
such system in a TL". Anyway, your additional info it is very useful to
me. Thanks.

The physical mechanism is the Z01==Z02 impedance discontinuity with
its associated reflection coefficient, rho. We can see that reflection
on a TDR so it is indeed a PHYSICAL mechanism.

Hello Cecil. I will try another translation because I think I could
not explain well my question.
We can see energy maximuns and nulls with simple experiments with
light. We set a double slits experiment and we see light flowing in
same direction reinforcing and cancellating in maximuns and minimuns
on screen. You name it "redistribution", the energy "dissapearing"
from nulls reappears on maximuns (Sorry, I use this horrifying light
example too because physics books have such unhealthy trend to explain
wave interference)
In a TL, instead, total destructive interference in one point would
mean energy stop flowing from that point forwards (is it OK say
"forwards"?) and reverse its flow direction doubling his value, is it
OK?. You name it "redistribution" too, not reflection. Well, my
question was how we can set (devise) an experiment to get such
behaviour in a TL? We need add (or put) in this point a source of
energy to make the interference (the second slit light source from the
light example, or the other front wave in a diffraction example), how
to, here?. Light experiments is easy because we put both independent
coherent light sources near each other illuminating the screen but
here I can not visualize how put them. I hope I was explain better my
question.
