This book focuses on practical computational electrodynamics, guiding the reader step-by-step through the modeling process from the initial 'what question must the model answer?', through the setting up of a computer model, to post processing, validation and optimization. The book offers a realistic view of the capabilities and limits of current 3-D field simulators and how to apply this knowledge efficiently to EM analysis and design of RF applications in modern communication systems.
