Hello, I'm having difficulty understanding exactly what the input power is for the port in the RF module in COMSOL 4.3. The unit is declared as watt, but unless there's some predefined thickness, the unit doesn't make sense (I would expect watt/m).
Just as an example, I tried simulating a silicon waveguide and set a line integration variable on the input where I measured the emw.Poavx (perpendicular to the line) at different lines on the waveguide and multiplied this value (which is in watt/m) by my expected thickness and got values that were much smaller than what I expected for what I put in as my input power.
Does this mean that the unit for input power in the port excitation is in fact watt/m? If so, that would explain some discrepancies in my other results I've been simulating.
