What RF engineers call "velocity factor" is related to the phase
constant in the complex propagation constant embedded in any
transmission line equation in any decent textbook. Do your
sources tell you anything about the complex propagation constant?


Complex propagation constant is ? = ? +j? :

Whe

? is the attenuation in Nepers/wavelength

? is the phase shift in Radians/wavelength

Did I pass ??????????
