Electrical Engineering/Electromagnetics Waves and Fields in Inhomogeneous Media A Volume in the IEEE Press Series on Electromagnetic Waves Donald G. Dudley, Series Editor ".it is one of the best wave propagation treatments to appear in many years." Gerardo G. Tango, CPG, Consulting Seismologist-Acoustician, Covington, LA This comprehensive text thoroughly covers fundamental wave propagation behaviors and computational techniques for waves in inhomogeneous media. The author describes powerful and sophisticated analytic and numerical methods to solve electromagnetic problems for complex media and geometry as well. Problems are presented as realistic models of actual situations which arise in the areas of optics, radio wave propagation, geophysical prospecting, nondestructive testing, biological sensing, and remote sensing. Key topics covered include:* Analytical methods for planarly, cylindrically and spherically layered media* Transient waves, including the Cagniard-de Hoop method* Variational methods for the scalar wave equation and the electromagnetic wave equation* Mode-matching techniques for inhomogeneous media* The Dyadic Green's function and its role in simplifying problem-solving in inhomogeneous media* Integral equation formulations and inverse problems* Time domain techniques for inhomogeneous mediaThis book will be of interest to electromagnetics and remote sensing engineers, physicists, scientists, and geophysicists. This IEEE Press reprinting of the 1990 version published by Van Nostrand Reinhold incorporates corrections and minor updating. Also in the series.

A comprehensive, step-by-step reference to the Nyström Method for solving Electromagnetic problems using integral equationsComputational electromagnetics studies the numerical methods or techniques that solve electromagnetic problems by computer programming. Currently, there are mainly three numerical methods for electromagnetic problems: the finite-difference time-domain (FDTD), finite element method (FEM), and integral equation methods (IEMs). In the IEMs, the method of moments (MoM) is the most widely used method, but much attention is being paid to the Nyström method as another IEM, because it possesses some unique merits which the MoM lacks. This book focuses on that method—providing information on everything that students and professionals working in the field need to know.Written by the top researchers in electromagnetics, this complete reference book is a consolidation of advances made in the use of the Nyström method for solving electromagnetic integral equations. It begins by introducing the fundamentals of the electromagnetic theory and computational electromagnetics, before proceeding to illustrate the advantages unique to the Nyström method through rigorous worked out examples and equations. Key topics include quadrature rules, singularity treatment techniques, applications to conducting and penetrable media, multiphysics electromagnetic problems, time-domain integral equations, inverse scattering problems and incorporation with multilevel fast multiple algorithm. Systematically introduces the fundamental principles, equations, and advantages of the Nyström method for solving electromagnetic problemsFeatures the unique benefits of using the Nyström method through numerical comparisons with other numerical and analytical methodsCovers a broad range of application examples that will point the way for future researchThe Nystrom Method in Electromagnetics is ideal for graduate students, senior undergraduates, and researchers studying engineering electromagnetics, computational methods, and applied mathematics. Practicing engineers and other industry professionals working in engineering electromagnetics and engineering mathematics will also find it to be incredibly helpful.

Lectures on Electromagnetic Field Theory: A Comprehensive Overview is for entry-level graduate students in electrical and computer engineering who want to have a comprehensive understanding of electromagnetic theory and its practical applications. This textbook covers topics from classical to quantum electromagnetics, as well as topics over a wide-frequency range, which can be applied from statics to extreme ultraviolet. The emphasis is on inculcating a physical and intuitive understanding of electromagnetics. The first part of the book covers the fundamentals, including constitutive relations, Green's function, boundary conditions, Poynting's theorem, gyrotropic media, and other important principles and theorems. The second part covers transmission lines, layered media, wave guidance, and resonance phenomena, including cavity quality factor. Homomorphism is used to connect layered media with transmission lines. The third part covers radiation by Hertzian dipole, antenna arrays, high frequency approximations, Sommerfeld integrals, and computational electromagnetics (CEM). This section introduces the rudiments of important concepts in CEM, including method of moments, finite element, and finite difference methods. The book ends by bridging the gap between classical and quantum by introducing students to quantum electromagnetics. This volume includes practical examples throughout and provides practice exercises to complement the individual chapter material.
