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'. ....Keith |
