IEVref: 131-15-33 ID: Language: en Status: Standard Term: complex voltage reflection factor Synonym1: complex tension reflection factor [Preferred] Synonym2: complex reflection coefficient (deprecated) [Preferred] Synonym3: Symbol: rrU Definition: ratio of the phasor representing the reflected voltage to the phasor representing the incident voltage at a port of an electric network or close to a discontinuity in a transmission line NOTE 1 – At a port of an electric network, the complex voltage reflection factor is by convention the negative of the complex current reflection factor. NOTE 2 – When impedances can be defined, the complex voltage reflection factor equals: $\underset{_}{r}=\frac{\underset{_}{Z}\prime -\underset{_}{Z}}{\underset{_}{Z}\prime +\underset{_}{Z}}$ where Z is the characteristic impedance of the transmission line ahead of the discontinuity or the impedance of the source, and Z′ is the impedance after the discontinuity or the load impedance seen from the junction between the source and the load. NOTE 3 – The terms "complex voltage reflection factor" and "complex tension reflection factor" may be shortened by omitting "complex" and/or "voltage" or "tension" in an appropriate context.
