Virtual reflection coefficients, such as the ones used by

What is a "Virtual reflection coefficients"?

SQRT(Pref/Pfor) which often differs from the
physical reflection coefficient (Z02-Z01)/(Z02+Z01)

So, what you are referring to with the term "virtual reflection
coefficient" is the magnitude the reflection coefficient (rho). or |(Z02-
Z01)/(Z02+Z01)| (Gamma).

Did you get that usage from an optics text?

I haven't seen "virtual reflection coefficient" used to have that
meaning. Nor have I seen hams commonly, as you suggest, using rho in the
way in which you could use S parameters or Gamma.

I did note that in a Google search, more than half the relevant hits on
the first page were your writings, so it is clear that you use the term.
