Voltage Standing Wave Ratio (VSWR) Formula

Voltage Standing Wave Ratio = (1+Reflection Coefficient)/(1-Reflection Coefficient)
VSWR = (1+Γ)/(1-Γ)

How are VSWR and reflection coefficient related?

A wave is partly reflected when a transmission line is terminated with an impedance unequal to its characteristic impedance. Reflection coefficient is a complex number that describes both the magnitude and the phase shift of the reflection and it directly corresponds to VSWR.
