Term: | complex current reflection factor | ||

Synonym1: | complex current reflection coefficient (deprecated) [Preferred] | ||

Synonym2: | |||

Synonym3: | |||

Symbol: | r_{I}
| ||

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 ′ is the impedance after the discontinuity or the load impedance seen from the junction between the source and the load.
ZNOTE 2 – The term "complex current reflection factor" may be shortened by omitting the qualifier "complex" in an appropriate context. | ||
