What software is recommended for designing microwave cavities?

[csopi]

Hi all,

I need a proper software for designing microwave cavities. I intend to use simple base geometries (e.g. closed box) with some modifications, like holes for optical access or for feeding the MW. These modifications however may seriously affect the Q factor, the frequency or might prevent some modes to develop etc. and I need to control these issues.

I would like to ask for a recommendation. Which software should I use? Any suggestions will be appreciated!

Sounds like a job for one of Ansoft's products. A quick search of "Ansoft microwave cavity" reveals many papers on the subject. They indicated that researchers use HFSS for simulating cavities.

Thank you, I'll look into it! Just out of curiosity: do you know any open source alternative?

google "open source 3d solver". I have no experience with any 3D solvers though.
