electromagnetic modeling codes - past and present

Computer modeling has become an important part of the design process for electronic systems. This one-day training session is intended to bring engineers up to date on the latest computer modeling tools and techniques available to help them design products that comply with electromagnetic compatibility requirements. The course covers electromagnetic modeling codes, circuit solvers, rule checkers, analytical modeling tools, web-based calculators and apps. Plenty of examples demonstrating the application of various modeling tools to real-world EMC design problems are provided. Students completing the course will be aware of the tools available to them and able to make good decisions regarding the tools that are appropriate for their needs.

Course Instructor

Prof. Todd Hubing

Dr. Todd H. Hubing is a Professor Emeritus of Electrical and Computer Engineering at Clemson University and Director of the Clemson Vehicular Electronics Laboratory. He and his students are the developers of EMAP, a hybrid FEM/BEM tool for electromagnetic modeling, as well as a number of online calculators used by EMC engineers. Over the past several years, he has had the opportunity to work with a wide variety of commercial computer modeling tools. Many of these tools have played an important role in his published research. In addition, Dr. Hubing has observed how EMC engineers in various industries are using commercial tools to develop better products. He and his students maintain a public database of electromagnetic modeling codes available on the Clemson Vehicular Electronics Laboratory website.
