Current reflection factor - opracowanie

Current re fl ection factor The current reflection factor Γi is defined by
Γi =
Ireγz
If e−γz . (2.76)
This definition is the obvious dual of the previously given definition in equation 2.52
for voltage reflection factor. Substituting for If and Ir in terms of Vf and Vr from
equations 2.48 and 2.49 we find that
Γi = −Γv . (2.77)
Then the relations between Γi and y are seen to be
Γi =
y − 1
y + 1
(2.78)
and y =
1 + Γi
1 − Γi
. (2.79)
These results now correspond in form to those of equations 2.70 and 2.69, a fact we
will make use of when we study in Chapter 3 the Smith Chart.
Note that the current reflection factor Γi transforms along the line in the same way
as does the voltage reflection factor Γv, i.e.
