Reflection coefficient is actually quite simple.
RC = (Z2-Z1)/(Z2+Z1)
I challenge you to find any reference with a different definition.

Sorry, all my references are at my new QTH but here are
a few from memory:

rho = SQRT(Pref/Pfor) = Vref/Vfor = Iref/Ifor = (SWR-1)/(SWR+1)

Yes, but these are less than useful aren't they. SQRT is
multi-valued so is never any use, and they all express
rho in terms of that which we want to derive rather than
in terms of that which we know. Means we need to know the
answer before we can compute the answer. Ooooopppps.

One of the options for preventing reflections (which can
really mess up the reception of the signal), is matching
at the source.

Yes of course, one can do that with a circulator or pad.

Or a single 10 cent resistor following the voltage or current
source. But I digress. Do look up "lattice diagram".
