And yes, |rho| can be greater than unity for a passive load.
But the power reflection coefficient cannot be greater than 1.0
which is what the argument is all about.
Which is entirely consistent with my previous statement:
It follows that when rho is greater than unity, it is not 'physically
meaningful to separate the total power as the sum of the incident and
reflected power' so the equation
|rho| = Sqrt(Pref/Pfwd)
has no meaning.
I suppose one might phrase it as 'there is no such thing as a power
reflection coefficient' when it is not 'physically meaningful to
separate the total power as the sum of the incident and reflected
power'.
