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.
