Free software to simulate circular waveguide

[Eugen_E]

Hello,

Do you know of a free program that can simulate a circular waveguide? I need it to analyze the field distribution in the waveguide and hopefully to design a coax to circular waveguide transition.
I'm not very interested in demos, because those are hard to get and limited to 30 days or less. I would prefer a free software,even if it is harder to use.
I tried emGine, but it only works for rectangular waveguides. Meep seems to work for any structure, but I couldn't find examples specific to RF&MW design, most of the examples available are for physics research.

Hi,

We commercialize software for what you want. If you are in the academia world and you plan to publish some results maybe we can send to you an evaluation license for some months, so you can do the work you need to do.
