This publication on the numerical design of RF-structures presents two topics: (1) An overview on Numerical Methods relevant for RF-resonator design; and (2) An introduction to Simulation Software that covers 2D and 3D software tools. These include RF-design basics, introduction to Finite Difference, Finite Element and other methods, concepts for problem descriptions, interaction with particles, couplers, mechanical and thermal design, and a list of tips, tricks and challenges. This is the summary of a tutorial that the author has twice presented at a recurring “Workshop on Microwave Cavities and Detectors for Axion Research” (2nd workshop on microwave cavities and detectors for Axion Research at Lawrence Livermore Laboratory, January 10–13th, 2017, https://indico.fnal.gov/conferenceDisplay.py?confId=13068). Differences between the design of RF-structures for Axion detection and RF-structures for traditional applications are pointed out, where appropriate. |
