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

Let's check this ``physical'' derivation against the formal definition
Eq. (N.31) leading to
in Eq. (N.33).
Define the total junction impedance as
Since
