Electromagnetic FieldsAn essential source of knowledge for experts working in electrical engineering and physics, this book gives an overview of the theory of electromagnetic fields and of the basic tenets of the analytical and numerical principles within the discipline. The first two chapters are devoted to the general theoretical background of electrodynamics, discussing static and steady-state phenomena in relation to dynamics. Chapter 3 and 4 are concerned with the analysis methods of electromagnetic fields based on partial differential equations. Chapters 5 and 6 offer various solution methods of electromagnetic fields. The principles and basic relationships of some approximate analysis methods of time invariant and time varying electric and magnetic fields are treated in chapters 7 and 8. Some important mathematical topics used in the book are summarized in the appendix. |
