EMC (electromagnetic compatibility)--Part 1: UNDERLYING CONCEPTS AND TECHNIQUES

Any serious study of electromagnetic compatibility (EMC) requires a reasonable background in several areas of electrical engineering. In a topic such as EMC, where the complexity of practical problems is very considerable, it’s not always possible to provide complete and accurate answers based on comprehensive quantitative models. In such cases it’s imperative that a basic underlying grasp of the nature of electrical components, their interactions through electromagnetic fields, and the nature and characterization of electrical signals is firmly established. Such a foundation provides the analyst and EMC designer with the basic conceptual framework and tools for asking the right questions, for critically evaluating results and assumptions, and for supporting the intuitive search for solutions based on sound scientific understanding. Even those who are not comfortable with mathematical models of physical systems and processes will benefit greatly from studying Part I, which is a distillation of the techniques most relevant to the study of EMC phenomena. Those already familiar with fields circuits and signals may also wish to study Part I, since it presents these topics from an EMC perspective.

The aim of the next four Sections is to provide background material on the nature and importance of EMC, the concept of electromagnetic fields, the description of real components in terms of ideal components, and the relationship between field and network concepts. Finally, the modeling and analysis of signals and circuits in the frequency and time domains will be described.
