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. Owen |
