Reflection Coefficient to Reflected Power Calculator

This tool calculates the reflected power from the reflection coefficient

Formula

Reflected Power (%) = 100*(|Γ|²)

where Γ is the reflection coefficient and 0 < Γ < 1

Background

The reflection coefficient is the ratio between the level of the incident waveform to the level of the reflected waveform.

The incident power P_INC is the sum of the reflected power P_R and forward power P_F.

The reflection coefficient

Γ = √(P_R/P_INC)

Expressed as a percentage,

Γ = √(P_R%/100)

P_R% = 100*(Γ²)

Example Calculation

For a reflection coefficient of 0, none of the power is reflected back and all of it is transmitted forward (an ideal situation).

For a reflection coefficient of 1, all of the power is reflected back (worst possible scenario).
