Have you computed the correct result then?

Yes, the results are identical with or without
the 1WL of 75 ohm lossless line, exactly as the
theory predicts it should be.

Have you read w2du's web page yet?

I am not sure where you are going with this. As you map
the system for s parameter evaluation, which is the two
port network that you are evaluating?

The generator's connection to the 450 ohm ladder-line.

An ideal source, as
used in this example, must be able to both source and sink
current. You will need to specify more for us to determine
whether the circuit you propose will achieve that to a
sufficient degree.

Actually, as the one asserting it is possible, the
onus of proof is upon you to come up with a real-
world design (besides the one in your dreams). I
predict you will need something like a circulator
to actually dissipate the reflected energy. Your
violation of the conservation of energy principle
just won't fly.
