Electromagnetic compatibility (EMC) may be approached from two standpoints. In the first approach, one is tempted to address the problem in its generality and seek the development of general tools to predict performance. The complexity of the problem is such that it is not at present possible to make decisive progress along this route and one is left with a collection of mathematical treatises of limited immediate applicability. It is also generally the case that a physical grasp of the problem cannot be easily attained in this way, since mathematical complexity dominates all. An alternative approach is to view EMC from the multiplicity of practical problems that confront designers on a day-to-day basis. The general appearance of such work is a collection of “EMC recipes and fixes” based on a mixture of theoretical ideas, practical experience, and black magic, which no doubt work under certain circumstances. The student of such works is left, however, without a clear physical grasp of exactly what is happening or an understanding of the range of validity of the formulae he or she is supplied with. The current text adopts a different viewpoint. Emphasis is placed on understanding the relevant electromagnetic interactions in increasingly complex systems. Mathematical tools are introduced as and when pursuing the physical picture unaided becomes counterproductive.
