Hi Duru,
Thank you for your screenshot, this was actually very helpful. I think you are using the FDE solver built in FDTD and the reason that you are not seeing losses in this case is because you are calculating a cross section of your waveguide, while in Interconnect you are measuring the losses of your whole waveguide. Now, for your additional questions, allow me a couple of days to work on them and I will come back.
