What software is recommended for designing microwave cavities?

Click For Summary
SUMMARY

The recommended software for designing microwave cavities is Ansoft HFSS, which is widely used for simulating cavities and managing modifications that affect the Q factor and frequency. Users have found HFSS effective for handling geometrical changes, such as adding holes for optical access or feeding microwaves. For those seeking open-source alternatives, a search for "open source 3D solver" is suggested, although the user expressed a lack of experience with 3D solvers.

PREREQUISITES
  • Understanding of microwave cavity design principles
  • Familiarity with Ansoft HFSS software
  • Basic knowledge of electromagnetic simulation
  • Awareness of Q factor and its significance in microwave applications
NEXT STEPS
  • Research Ansoft HFSS features and capabilities for microwave cavity simulation
  • Explore open-source 3D solvers suitable for microwave applications
  • Study the impact of geometrical modifications on Q factor and frequency
  • Investigate academic papers on microwave cavity design using HFSS
USEFUL FOR

Engineers and researchers involved in microwave engineering, particularly those focused on cavity design and simulation, will benefit from this discussion.

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.
