Electromagnetic Theory and Modeling

It is well established that electromagnetic theory forms the backbone of electromagnetic interference and compatibility work. A good understanding of electromagnetic theory is highly desirable; however, it does not by itself lead to an understanding of the complexities of the electromagnetic interference phenomenon. This is because the interactions of electromagnetic fields with complex objects, as would be the case in real applications, cannot simply be predicted without abstraction of reality or, in other words, without creating a model of the physical system being analyzed. Creating an electromagnetic model that faithfully resembles the electromagnetic field behavior in the physical world is a challenging exercise that requires basic understanding of electromagnetic theory but would also require a good understanding of circuit theory, and of course, a sense of which physical factors are relevant to the model.
