Definition: the ratio, along a transmission line, of a maximum to an adjacent minimum magnitude of a particular field component of a standing wave

NOTE 1 – This ratio is equal to: (1 + r) / (1 — r) where r is the modulus of the amplitude reflection factor.

NOTE 2 – The standing-wave ratio expressed as the reciprocal of the ratio defined above is occasionally used, but this usage is deprecated.
