Christmas 2024 Reflection Coefficient. \ (rc\) is the reflection coefficient, \ (v_r\) is the voltage of the reflected. A reflection coefficient is defined at the junction between two media, usually transmission lines, of different impedance.

So the general equation for the reflectivity at the interface between two materials is given by: Reflection coefficient ( ?), return loss (rl), and voltage standing wave ratio (vswr) are related.
