This book is a comprehensive guide to computer simulations for Electromagnetic Compatibility (EMC) in electronic systems. It brings together the key domains a simulation engineer must master—circuit simulation, field simulation, numerical methods, and expertise in EMC phenomena—to effectively model, analyze and predict the EMC of electronic systems. Using classical EMC scenarios as case studies, the book demonstrates how simulation supports design decisions and performance predictions, with a focus on industrial applications and efficient simulation workflows. A consistent modeling approach is followed throughout: every EMC problem is decomposed into source, coupling path, and sink, with appropriate modeling techniques introduced for each part. Early chapters introduce circuit-level models and field simulation methods. As the book progresses, more advanced numerical methods and simulation workflows are introduced, enabling the simulation of complex EMC challenges. In the later sections, simulations based on standardized EMC test setups are explored. These typically involve large, computationally demanding models—here, strategies for model simplification and their impact on results are examined. Key Features: A complete framework for EMC simulation using combined circuit and field simulation Step-by-step guidance on how to virtually analyze and predict the EMC of electronic systems Practical, industry-related examples that reflect common challenges faced by EMC engineers More than 150 simulation models based on CST Studio Suite are available through Springer’s GitHub repository
