IEVref: 131-15-32 ID: Language: en Status: Standard Term: complex current reflection factor Synonym1: complex current reflection coefficient (deprecated) [Preferred] Synonym2: Synonym3: Symbol: rI Definition: ratio of the phasor representing the reflected electric current to the phasor representing the incident current at a port of an electric network or close to a discontinuity in a transmission line NOTE 1 – When impedances can be defined, the complex current reflection factor equals: ${\underset{_}{r}}_{I}=\frac{\underset{_}{Z}-\underset{_}{Z}\prime }{\underset{_}{Z}+\underset{_}{Z}\prime }$ 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 2 – The term "complex current reflection factor" may be shortened by omitting the qualifier "complex" in an appropriate context.
