Description

This book will cover advances in computational electromagnetics by examining similar problems with different approaches related to antenna theory models and transmission line methods. It discusses different solution methods related to boundary integral equation techniques and finite difference techniques. The book offers a trade-off between the different formulations and numerical solution methods is provided. The most significant topics covered in the book are related to realistic antenna systems (e.g. antennas for air traffic control), grounding systems (e.g. for grounding systems for wind turbines), biomedical applications of electromagnetic fields (e.g. trans cranial magnetic stimulation), etc. The book includes a large number of illustrative computational examples and reference list at the end of each chapter. Rigorous theoretical background and mathematical details of various formulations and solution methods being used throughout the book are presented in the corresponding appendices.
