I can see that within this thread we have at least
three expectations of what happens within the source
when a reflection arrives; absorbed, controled
reflection, and acts like a short.

Since a short causes a reflection, it seems that
(2) and (3) are essentially the same thing and
since 0+j0 cannot absorb energy and always
reflects energy, seems (1) can be discarded as
an over-simplification, something for which the
lumped circuit model is famous. For instance:

Given a loading coil installed in a traveling
wave antenna - reckon why EZNEC gives completely
different delays through the inductance when it
is modeled as a lumped inductance vs when it is
modeled using EZNEC's helix feature?
