This seems to be at odds with explanation that SGCL#1's power is dissipated in SGCL#2's circulator load resistor since there is no energy flowing at the voltage maximum. Nope, a directional coupler can still separate out the forward and reflected waves even at voltage and current nulls. It is a bit early to move to the complexity of directional couplers. I am still stuck on how energy can flow through a point on the circuit where the current or voltage is always 0. Using instantaneous Power = Vinst x Iinst, the power at such a point must always be 0, leading to the conclusion that no energy is flowing. So how does energy flow through a point in the circuit where the voltage or current is always 0. Is it that Pinst != Vinst x Iinst? Or is it that there is no point in the ideal experiment presented where V or I is always 0? Or have I missed something in the chain of reasoning above? ....Keith |
