I am trying to understand forward and reflection power
throught practical circuits , instead of going through books.

I found forward/reverse power meters measure reverse
power by measuring the phase difference between current
and voltage at load terminals. If current and voltage
are in phase, there is no reflection . am i correct ?

if it is correct ,
if transmitter has 50+j0 ohm output impedance , and if i connect
antenna tuned to 100+j0 ohm. (assume no long cable is used ,
directly connected ) , reverse power is zero ?
