Electromagnetic Fields: Restrictions and Approximation

Detailed Summary

In "Electromagnetic Fields: Restrictions and Approximation", Boris Z. Katsenelenbaum methodically examines the nature of electromagnetic phenomena through an academic yet highly practical lens. The book begins with an analysis of foundational electromagnetic equations, such as Maxwell's equations, and demonstrates how assumptions, restrictions, and boundary conditions are critical to understanding behavior in both idealized and complex systems.

A substantial portion of the text is devoted to approximation methods. These methods are designed to simplify the mathematical formulation of electromagnetic problems while retaining the essential physics behind them. Topics such as perturbation methods, asymptotic analysis, and variational principles are discussed in detail. The author also presents unique approaches to applying these techniques to exotic systems, such as waveguides, resonators, and scattering problems.

Drawing from decades of research and practical experience, the author provides readers with examples from real-world applications, including telecommunications, antenna design, and optics. By marrying theory and practice, this book transcends the ordinary treatment of electromagnetic fields and offers an exceptional guide for aspiring researchers and seasoned professionals.
