Calculation method
Calculation method
Reflection magnitude
sqrt(reflected/forward).
Voltage standing-wave ratio
(1+rho)/(1−rho).
Return loss (dB)
−20 log10(rho); zero reflection gives no finite return loss.

Assumptions & limits
Assumptions & limits
- Forward-reflected power or reflection magnitude. Returns VSWR and return loss. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Forward power (W): minimum 1e-12, maximum 1000000000000.0. Reflected power (W): minimum 0, maximum 1000000000000.0.
