Book Description
Dieses Buch beinhaltet eine Sammlung hierarchisch strukturierter Beispiele zur Demonstration der Leistungsfähigkeit heutiger Simulationssysteme zur Analyse der Störemissionen von Leiterplatten. Sind die geometrischen Strukturen von relativ einfacher Komplexität, wird auf das numerische Verfahren der Momentenmethode zurückgegriffen. Diese Methode ermöglicht eine sehr genaue Analyse aller physikalisch relevanten Mechanismen der Emission und Absorption elektromagnetischer Strahlung. Jedoch kann bei realen Leiterplatten die geometrische Komplexität durch viele tausend Verbindungsleitungen in einem Multilayerdesign gegeben sein, für die numerische Verfahren wie die Momentenmethode nicht mehr einsetzbar sind. Zur Lösung derartig komplexer Beispiele wird alternativ ein Verfahren vorgestellt, das als Expertensystem aufzubauen ist. Obwohl dieser Ansatz die physikalische Natur der Ab- und Einstrahlungsmechanismen nicht vollständig abbilden kann, scheint es derzeit der einzig realisierbare Weg zur Schaffung eines rechnergestützten Analysewerkzeuges zur Abschätzung des Strahlungsverhaltens von Leiterplatten zu sein.

Book Description
Modeling and Design of Electromagnetic Compatibility for High-Speed Printed Circuit Boards and Packaging presents the electromagnetic modelling and design of three major electromagnetic compatibility (EMC) issues related to the high-speed printed circuit board (PCB) and electronic packages: signal integrity (SI), power integrity (PI), and electromagnetic interference (EMI). The emphasis is put on two essential passive components of PCBs and packages: the power distribution network and the signal distribution network. This book includes two parts. Part one talks about the field-circuit hybrid methods used for the EMC modeling, including the modal method, the integral equation method, the cylindrical wave expansion method and the de-embedding method. Part two illustrates EMC design methods and explores the applications of novel metamaterials and two-dimensional materials on traditional EMC problems. This book is designed to enhance worthwhile electromagnetic theory and mathematical methods for practical engineers and to train students with advanced EMC applications.

Book Description
GROUNDS FOR GROUNDING Gain a comprehensive understanding of all aspects of grounding theory and application in this new, expanded edition Grounding design and installation are crucial to ensure the safety and performance of any electrical or electronic system irrespective of size. Successful grounding design requires a thorough familiarity with theory combined with practical experience with real-world systems. Rarely taught in schools due to its complexity, identifying and implementing the appropriate solution to grounding problems is nevertheless a vital skill in the industrial world for any electrical engineer. In Grounds for Grounding, readers will discover a complete and thorough approach to the topic that blends theory and practice to demonstrate that a few rules apply to many applications. The book provides basic concepts of Electromagnetic Compatibility (EMC) that act as the foundation for understanding grounding theory and its applications. Each avenue of grounding is covered in its own chapter, topics from safety aspects in facilities, lightning, and NEMP to printed circuit board, cable shields, and enclosure grounding, and more. Grounds for Grounding readers will also find: Revised and updated information presented in every chapter New chapters on grounding for generators, uninterruptible power sources (UPSs) New appendices including a grounding design checklist, grounding documentation content, and grounding verification procedures Grounds for Grounding is a useful reference for engineers in circuit design, equipment, and systems, as well as power engineers, platform, and facility designers.

Book Description
This book provides a sound grasp of the fundamental concepts, applications, and practice of EMC. Developments in recent years have resulted in further increases in electrical component density, wider penetration of wireless technologies, and a significant increase in complexity of electrical and electronic equipment. New materials, which can be customized to meet EMC needs, have been introduced. Considerable progress has been made in developing numerical tools for complete system EMC simulation. EMC is now a central consideration in all industrial sectors. Maintaining the holistic approach of the previous edition of Principles and Techniques of Electromagnetic Compatibility, the Third Edition updates coverage of EMC to reflects recent important developments. What is new in the Third Edition? A comprehensive treatment of new materials (meta- and nano-) and their impact on EMC Numerical modelling of complex systems and complexity reduction methods Impact of wireless technologies and the Internet of Things (IoT) on EMC Testing in reverberation chambers, and in the time-domain A comprehensive treatment of the scope and development of stochastic models for EMC EMC issues encountered in automotive, railway, aerospace, and marine applications Impact of EMC and Intentional EMI (IEMI) on infrastructure, and risk assessment In addition to updating material, new references, examples, and appendices were added to offer further support to readers interested in exploring further. As in previous editions, the emphasis is on building a sound theoretical framework, and demonstrating how it can be turned to practical use in challenging applications. The expectation is that this approach will serve EMC engineers through the inevitable future technological shifts and developments.
