Physical Derivation of Series Reflection Coefficient
Physically, the force-wave reflection coefficient seen at port of a series adaptor is due to an impedance step from , that of the port interface, to a new impedance consisting of the series combination of all other port impedances meeting at the junction. Let
denote this series combination. Then we must have, as in Eq.(F.25),
(F.36) |
Let's check this ``physical'' derivation against the formal definition Eq.(F.31) leading to in Eq.(F.33). Define the total junction impedance as
Since
