So I stopped talking about "reflected power" and

to the use of the term "reflected energy". Would you and
the rest of the guru attack gang please get together on
what term you would like for me to use?
NEITHER! they are both confusing. use the most fundamental things
that you can measure, either voltage or current. either one is
completely defined in the basic maxwell equations, and either one is
completely sufficient to describe ALL effect on a cable or in any
circuit.
If Maxwell's equations could be used to answer the
questions that we are asking, why haven't they been
answered a long time ago?
How can Maxwell's equations be used to track the path
and fate of the energy in a reflected wave?
Cecil,
There may be some terminology confusion here.
Maxwell's equations are really the only relevant physical equations
there are to work with, at least in the classical regime. The discussion
about constructive, destructive, superposition, linearity, etc.
represents merely mathematical manipulation of the basic physical
entities embodied in Maxwell's equations.
All of this *math* is of course very important and very useful. However,
it is not a replacement for the *physical* laws known as the Maxwell
equations.
(And we all know that these endless threads are closely parallel to the
blind men describing an elephant puzzle.)
