Features: Electromagnetic compatibility (EMC) is an emerging interdisciplinary and marginal discipline. With the development of science and technology, the interpenetration and integration of multiple disciplines have made the application of electronic or electrical equipment increasingly widespread, leading to growing emphasis on EMC technology in many fields. Any electronic or electrical device, when operating, emits electromagnetic energy to its surroundings, which may cause interference to the normal operation of other devices. At the same time, the device itself may also be affected by the surrounding electromagnetic environment. The main issue of EMC research is how to ensure that various devices and systems operating in the same electromagnetic environment can function normally without interfering with each other. This book begins with the concept of electromagnetic interference and systematically analyzes various specific methods that should be adopted for different interference sources and pathways, focusing on the design of EMC environments. Topics covered include interference between wires and shielding measures, interference caused by grounding and ground impedance, radiated common-mode interference and ground loop interference, radiated differential-mode interference, interference from power lines and power systems, and the sources and control of electromagnetic interference. The book is comprehensive and rich in content, with exercises and partial solutions provided after each chapter, as well as practical charts and diagrams for reference during experiments and design. It is highly suitable for engineering technicians engaged in the design, manufacturing, use, and maintenance of electronic or electrical systems, and can also serve as a textbook or reference for relevant majors in higher education institutions.
