Dear all,
does somebody know how to define an electromagnetic field in RF/Waveoptics (comsol v.4.3a) module ANALYTICALLY using solution of Fresnel equations, not using ports?
For air-glass interface for instance. I need it for later to solve scattering on nanoparticle (does not want to do like in "scatterer on the substrate", want to have precise analytic solution for background field in the absence of scatterer).
I tried sending analytic solution of Fresnel equations from the side using "Ports" or "Electric field" option in "Full field interface" as well as typing in the analytic expressions for the field in "Background field" in "Scattered field interface", but it does not work.
Does smb have an idea? Thanks in advance
Best regards
Pavel
