That said, I take exception with your
statement regarding the
bi-directionality of the simulated
coaxial transmission lines in available
NEC(n) engines. Their simulations are
uni-directional - from the input to the
load, but not in reverse.

That is patently false, and can be easily demonstrated. The transmission
line model in NEC (and EZNEC) is a linear network which is completely
bidirectional.


Roy,

Linear, yes... bi-directional? Not as I see
it... and leaves one wondering why NEC3
is available only to government entities
and contractors...

To confirm your claim, please post a
demonstration that confirms energy in the
load is flowing into the input.

Also, please repost your reply to my post
with the header "another lie..." as it did not
show up in my newsreader.

Thanks,
