  • 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.

  • 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.

  • 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 non-linear 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. ...
