Classical Electrodynamics
About this book
The new edition of this classic work in electrodynamics has been completely revised and updated to reflect recent developments in experimental data and laser technology. It is suitable as a reference for practicing physicists and engineers and it provides a basis for further study in classical and quantum electrodynamics, telecommunications, radiation, antennas, astrophysics, etc. The book can be used in standard courses in electrodynamics, electromagnetic theory, and lasers. Paying close attention to the experimental evidence as the basis for the theoretical development, the book’s first five chapters follow the traditional introduction to vector calculus, electrostatic field and potential, BVPs, dielectrics, and electric energy. Chapters 6 and 7 provide an overview of the physical foundations of special relativity and of the four-dimensional tensor formalism. In Chapter 8, the union of Coulomb’s law with the laws of special relativity gives issue to the relativistic form of Maxwell’s equations. The book concludes with applications of Maxwell’s equations in Chapters 9 through 16: magnetostatics, induction, magnetic materials, electromagnetic waves, radiation, waveguides, and scattering and diffraction. Numerous examples and exercises are included. Features +Designed as a text/reference for students, practicing physicists, and engineers +Updated in the second edition, including a discussion of the concept of negative oscillator strengths and a new section dealing with lasers and the threshold condition for lasing;revised experimental data (especially in the chapter dealing with relativity); expanded explanations, additional examples and exercises +Explores areas of contact between classical electrodynamics and quantum physics, such as electrostatic energy of nuclei, image charges as confinement mechanism for free electrons, magnetic monopoles, angular momentum in electromagnetic waves, radiation by atoms and nuclei, and lasers.
