The tricky part is measuring this correctly, because you
would need an SWR meter that is calibrated for the same Z as
Zo.
It is not nearly that tricky. 'Revised' rho, as you state,
predicts 0 Volts across the capacitor. This will be easy to
measure with any AC voltmeter that can handle your test frequency.
Perhaps, but i'm interested in the forward and reflected
waves, which you can only get with directional couplers on a line of
the same Z as the Zo, i suspect. So even if you get 0 volts, there
are still fwd and rev waves.
But what if you do not get zero volts. Sort of messes up the
'revised' rho theory a bit, does it not?
the 'revised' rho predicts zero reflect 'power waves' as defined by
kurokawa... it says nothing about voltage or current waves.
So is kurokawa proposing two completely different rhos?
One for computing voltages and currents and the other for power?
This could work, I supposed, but this discussion started with an
assertion that 'classic' rho was WRONG because it resulted in
more reflected power than incident. My contention is that
'classic' rho is correct and yields the correct voltages regardless
of the results obtained when |rho|^2 is used to predict powers.
If kurokawa wishes to introduce a new rho to solve these problems
in a different manner, that is fine, but he would have reduced
confusion significantly if he had not called it rho.
