Reflection coefficient from ratio of average power to incident power

Knowing the average power delivered to the load and the incident power, it is possible to calculate the absolute value of the reflection coefficient.

avg(P) / P_incident = 1 - Abs(Gamma)^2

Latex:
\[\frac{\langle P \rangle}{P_\text{incident}} = 1 - \left|{\Gamma}\right|^{2}\]
