On the basis of vector analysis, fundamental concepts of electromagnetic fields are introduced starting from the experimental laws of electromagnetics, and the basic laws governing the entire electromagnetic phenomena in macro world -- Maxwell's equations are established in free space. Then Maxwell's equations are extended to materials, and boundary conditions are emphasized. Static fields are introduced as special cases of Maxwell's equations and methodologies such as method of images and separation of variables for solving boundary value problems are discussed in detail. Relationship between field theory and circuit theory are covered as a bridge, and applied to the calculation of distributed parameters for some common electromagnetic devices. Time-varying fields as the main focus of this book are introduced, covering the propagation characteristics of uniform plane wave in lossless and lossy media, and across an impedance boundary for normal and oblique incidence cases. In the end, fundamental radiation systems are mentioned.
This book can be used as a textbook for undergraduate students majoring electronic information and communication engineering to learn the course of electromagnetic fields and waves, and also as a reference for relevant engineering technicians.
