Why the injecteed power from an input port of a two port network is not "1"?
I am trying to simulate a two-port network across a waveguide. The input port is injecting power. In principle the injected power should be equal to 1 and will decay across its way.
However, if I plot the power profile of the input port it shows only 0.3 and after a certain distance of around 50 µm of travel it becomes 0.1. Why the power "P" profile does not show me 1?
