This tool calculates the reflected power from the reflection coefficient
Reflected Power (%) = 100*(|Γ|2)
where Γ is the reflection coefficient and 0 < Γ < 1
The reflection coefficient is the ratio between the level of the incident waveform to the level of the reflected waveform.
The incident power PINC is the sum of the reflected power PR and forward power PF.
The reflection coefficient
Γ = √(PR/PINC)
Expressed as a percentage,
Γ = √(PR%/100)
PR% = 100*(Γ2)
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).
