10.8.4.1 Method I
The experimental setup is shown in Figure 10.22. First, the location of min-
ima (say L
1
) is noted without locating the DUT in the setup. Later, the device
is inserted and the new location of minima (say L
2
) is noted. The network
insertion will introduce a phase shift [ (L
2
~ L
1
)
λ
]. Since one
λ
is equivalent
to the phase shift (
ϕ
) of 360
°
or 2π radians the value of
ϕ
can be calculated. The
change of phase of a component or network due to variation of some param-
eter is sometimes desired. As an example consider the movement of a dielec-
tric rod inside a waveguide from one end to the mid-position or ...
