Theory of Electromagnetic Beams

Theory of Electromagnetic Beams by John Lekner, John Lekner. - 1st edition 2020 - 1 recurso en línea (XVII, 165 páginas) - Synthesis Lectures on Engineering Science and Technology 2690-0327 .
Preface -- Acknowledgments -- Fundamentals -- Beam-Like Solutions of the Helmholtz Equation -- Electromagnetic Beams -- Polarization -- Chirality -- Comparison of Electromagnetic Beams -- Sound Beams and Particle Beams -- Measures of Focal Extent -- Author's Biography.
The theory of electromagnetic beams is presented in a simple and physical way, with all necessary mathematics explained in the text. The topics covered are in free-space classical electrodynamics, but contact is made with quantum theory in proofs that causal beams of various kinds can be viewed as superpositions of photons. This follows from explicit expressions for the energy, momentum and angular momentum per unit length for each type of beam. The properties of beams in the focal region, of special experimental and theoretical interest, are discussed in detail. There are eight chapters: on Fundamentals, Beam-like solutions of the Helmholtz equation, Electromagnetic beams, Polarization, Chirality, Comparison of electromagnetic beams, a chapter on Sound beams and particle beams (to show the similarities to and differences from the vector electromagnetic beams), and a final chapter on Measures of focal extent. Ten Appendices cover mathematical or associated physical topics.
