Course Instructor

Professor Todd Hubing

Dr. Todd H. Hubing is a Professor Emeritus of Electrical and Computer Engineering at Clemson University and former 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.
