It's only loaded with the conservation of energy
principle, Reg. Here's a simple example. The SG-CR
is a 50 ohm signal generator equipped with a
circulator resistor to dissipate all reflected
power incident upon the source.

200W SG-CR---one second long lossless 50 ohm line---291.42 ohm

SWR is 5.83:1 rho^2 = 0.5 Steady-state forward power
is 200 watts. Steady-state reflected power is 100 watts.

The question is: After steady-state has been reached, how
many joules of energy have been generated but have not been
dissipated in the load resistor or circulator resistor?
