And this shows us that if [rho] is greater than one, the reflected
power will be greater than the incident power.

Maybe, or maybe the equation assumes Z0 is not complex. I don't know
the assumptions. Which leads to another question. Can the index of
refraction for a material be complex? To the best of my knowledge,
there's no mention of complex indices of refraction in _Optics_.

... most of the literature has rho=[gamma].
Where gamma is the complex reflection coefficient, and rho is only the
magnitude.

That is the convention I use. Unfortunately, it is not universal and may
even be old-fashioned, like me. :-)
