Voltage variation along a line - wykład

Voltage variation along a line We look at the way the total voltage V(z) varies along the lossless line. We have from
equation 2.42, with γ = jβ
V(z) = Vfe−jβz +Vre+jβz (2.82)
where Vf and Vr are complex numbers. As we go along the line, we will have in
equation 2.82 the two terms moving in and out of phase, the resultant voltage magnitude
having the form shown in Figure 2.24.
Note there are two maxima in each wave length. The maximum and minimum values
of the voltage magnitude.
Note that the incident wave will always be greater in magnitude than the reflected
wave whenever the reflected wave comes from a passive termination, so that the last
equation always produces a positive value.
