Electromagnetics and Calculation of Fields

About this book

This introduction to electromagnetics emphasizes the computation of electromagnetic fields and the development of theoretical relations. Beginning with the idea that Maxwell's equations are primary, the authors avoid the lengthy discussions of electro- and magneto-statics that are customary in texts on electromagnetism. Thus, after a chapter on the basics of vector calculus, the discussion begins with the electromagnetic field and maxwell's equations; the two following chapters then present the special cases of electrostatic and magnetostatic phenomena. Dynamics is introduced in Chap. 5, and electromagnetic induction in Chap. 6. The discussion of wave propagation and high-frequency fields emphasizes such practical matters as propagation in lossy dielectrics, waveguides, and resonators. The remaining four chapters discuss computational techniques: the finite element method, Galerkin's residual approach, software implementation, and recent developments in computer techniques.
