Electromagnetic modelling for EMC

Electromagnetic compatibility is a significant application area for electromagnetic modelling techniques. There is strong industrial interest in the development of numerical simulation methods that could allow EMC issues to be investigated in the early stages of design. Although modelling the functional EMC performance of complex systems remains challenging, for both technical and practical reasons, EM modelling of large and complex structures is already possible with relatively modest computing resources. As the results obtained from EM models do not directly provide the parameters of interest for EMC analysis, indirect approaches are needed to exploit EM model results in support of EMC engineering. This paper outlines some strategies employed in the automotive industry to support vehicle EMC engineering using EM models.
