Hi,

I am a beginner with COMSOL.

I have made a simulation in which I have waveguide which bends. I have found the Electric field. I want to compute the bending loss by comparing the total intensity/power at input and output. Please see the attached file.

Thank you.

Best regards,
Nirmalendu Acharyya

Have you tried Derived Values -> Global Evaluation -> -20*log10(ewfd.S21)? Didn't look at your file.
