Homogeneous 1d resistant line

At high frequencies, the expression for can be presented in an approximate form

The parameter _r at the limit passing has to be considered also jointly with the coefficient (2n - 1). Noting (17), (29) and (30), we yield

where

is the wave coefficient of a resistant line.

It is characteristic that at 0  (34) automatically transforms to a conventional

In resistant lines, the phase of wave delay _r depends on frequency in a complicated way. Just as in case with , the resistance effect on k_r is especially seeing at low frequencies, when / was comparable with . At high frequencies, (34) can be approximately presented as

We can see from (34) and (36) that k_r also depends on /.
