Hi all
Does anybody knows how to set "identiy pair" as "port" in Comsol 4.0a or 4.1? I am calculating the reflectance and transmittance in Comsol. Previously, I used Comsol 3.5a for this work (refer to: www.comsol.com/showroom/gallery/6141/ ) and it worked quite well. However, in the new Comsol, it seems that this function is lost and if I do this no field can be seen. I have tried other ways to calculation R and T, e.g., using scattering boundary or port without setting PML, however, the results are not very good due to the reflection of the scattering interface under tilted incidence.
Actually, what I am interested in is putting a PML above a port source and the incident light go only into the structure without going into the PML (only reflected light will enter PML). In old version of Comsol, we cannot set interior boundary as port, so "assembly" must be used. In the new Comsol, however, although interioe boundary can be set as port, the light goes to both directions.
It will be very appreciated if any of you can provide me some information about this problem.
Cheers
