Term: complex voltage reflection factor

[Preferred]
Synonym2: complex reflection coefficient (deprecated)

Symbol: r
rU
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:

r _ = Z _ Z _ Z _ + Z _ MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaieYdi9WrpeeC0lXdi9qqqj=hEeeu0lXdbb a9frFj0xb9Lqpepeea0xd9s8qiYRWxGi6xij=hbba9q8aq0=yq=He9 q8qiLsFr0=vr0=vr0db8meaabaGacmGadiWaaiWabaabaiaafaaake aadaadaaqaaKqzafGaamOCaaaacqGH9aqpkmaalaaabaWaaWaaaeaa jugqbiaadQfaaaGaam4jaiabgkHiTOWaaWaaaeaajugqbiaadQfaaa aakeaadaadaaqaaKqzafGaamOwaaaacaWGNaGaey4kaSIcdaadaaqa aKqzafGaamOwaaaaaaaaaa@461F@

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.
