Where are these equations? I have searched the ARRL handbook for Gamma
and did not find it. This is also the first reference to rho.
Some texts, like ITT's "Reference Data for Radio Engineers"
simply define rho to be complex as does Ramo and Whinnery.
rho = Eref/Efor = -Iref/Ifor = (Z-Z0)/(Z+Z0) =
(Y0-Y)/(Y0+Y) = |rho| /_ 2*psi
where psi is the electrical angle to the nearest voltage
maximum looking back toward the generator from the load.
Walter C. Johnson uses 'k' for the reflection coefficient.
