Hello, and it would be more correct to say that the forward and reflected waves are components of a standing wave. However a circulator plus load resistor located at the source will prevent reflected wave energy from being incident upon the source and will heat up that load resistor in the process proving that reflected waves are real and do contain energy. Hmm. Don't quite get that. Say an RF voltage source is located at port A of an ideal 3-port circulator designed for a system (characteristic) impedance of Zo. A load of ZL terminates port B and a load of Zo is attached to port C. Now, incident energy from the source at A is transferred by circulator action to the load at port B. If ZL is not equal to Zo then reflected energy from port B is transferred to port C where it is dissipated in the port C termination. None of the reflected energy originating from port B ever returns to port A in this ideal case (circulator has infinite isolation).
