Hi.
I have a resonator inside background media. I use PML around. I am looking at a particular mode. Then I can find the maximum of normE field which is inside the resonator. Now if I change the size of background media normE max is changed!! Although the resonator shouldnt be affected by the size of background media.
Is it possible that comsol normalizes modes to the computational volume?

Victoriia,
I assume you are using eigenvalue solver. Comsol normalizes eigenfunctions internally – so the magnitude of the resonant mode means nothing. What is important is the shape of the resonant modes and the he magnitude of the eigenvalues (which are resonant frequencies).

Sergei
