If I want to use an open boundary condition in my mode,which kind of boundary setting is corresponding to ? scattering filed or matched layer? Noticing that I want to calculate the eigenmode/eigenfrequency,For example, the eigen mode in a waveguide? How can I calculate it ?Which mode should I use.Thanks in advance.

Hi
Well my response is a "réponse de Normand" I believe (each country has its own designation of that), I would say: "it depends".
The difference with COMSOL and other FEM programmes is that COMSOl is "open physics", while most others are pre-cooked engineering approaches (very roughly).
So my only advise is to re-read the RF docs and do several of the related exercices (as well as some of the ones you can find on the comsol web site). There are seveal on the pml's and on different waveguides cases.
Your case is it 2D or 3D (2D is preferred to start with until one masters the details), and which complexity ? ...
Thereafter you most probably will have the response as it applies specifically for your case.
Even better for a "kick start", if you are new to COMSOL RF, is to follow one of the advanced RF courses organised by COMSOL.
Sorry for not being more precise.
Have fun Comsoling
