Field and Wave Electromagnetics (eBook, PDF)

Pearson New International Edition

• Format: PDF

Produktbeschreibung

Respected for its accuracy, its smooth and logical flow of ideas, and its clear presentation, Field and Wave Electromagnetics has become an established textbook in the field of electromagnetics. This book builds the electromagnetic model using an axiomatic approach in steps: first for static electric fields, then for static magnetic fields, and finally for time-varying fields leading to Maxwell's equations. This approach results in an organised and systematic development of the subject matter. Applications of derived relations to fundamental phenomena and electromagnetic technologies are explained.
