Electromagnetism

We have known the close connection between changing eletric fields and magnetic fields. They can create each other and form a system of electromagnetic fields. Electromagnetic fields can propagate in the space (vacuum or material environment). We call them electromagnetic waves. They play a very important role in science and technology.

This volume, derived from the Handbook of Engineering Electromagnetics (2004), is intended as a desk reference for the fundamentals of engineering electromagnetics. Because electromagnetics provides the underpinnings for many technological fields such as wireless communications, fiber optics, microwave engineering, radar, electromagnetic compatibility, material science, and biomedicine, there is a great deal of interest and need for training in the concepts of engineering electromagnetics.

The study of electromagnetic radiation (EM) can be divided into two distinct areas: full solution of Maxwell's Equations relevant to the specific boundary conditions in a special general case and into application of EM radiation that results in modern life e.g. medicine, telecommunication, electromagnetic compatibility (EMC) etc. The reader should have a specific scientific background and must be familiar with the fundamental ideas of EM theory for the first area. Basic understanding of applying the radiation techniques in modern life is needed for the second.

Among the branches of classical physics, electromagnetism is the domain which experiences the most spectacular development, both in its fundamental and practical aspects. The quantum corrections which generate nonlinear terms of the standard Maxwell equations, their specific form in curved spaces, whose predictions can be confronted with the cosmic polarization rotation, or the topological model of electromagnetism, constructed with electromagnetic knots, are significant examples of recent theoretical developments. ...

This is a companion volume to Electromagnetism for Electronic Engineers (3rd edn.) (Ventus, 2009). It contains the worked examples, together with worked solutions to the end of chapter examples, which featured in the previous edition of the book. I have discovered and corrected a number of mistakes in the previous edition.

In this volume I present some examples of napla calculus, vector potentials, Green’s identities, curvilinear coordinates , Electromagnetism and various other types, cf. also Calculus 2b, Functions of Several Variables. Since my aim also has been to demonstrate some solution strategy I have as far as possible structured the examples according to the following form A Awareness, i.e. a short description of what is the problem. D Decision, i.e. a reflection over what should be done with the problem. I Implementation, i.e. where all the calculations are made. C Control, i.e.

This introduction to electromagnetic theory emphasises on applications in electronic engineering. The book explores the relationship between fundamental principles and the idealisations of electric circuit theory. Attention is drawn to the effects of parasitic capacitance and inductance, to electromagnetic screening and to the effects of propagation delay.
