Integral equation techniques in transient electromagnetics by D. Poljak, , WIT edition, in EnglishCited by: Abstract. Transient and broadband electromagnetic scattering and radiation phenomena involving perfect electrically conducting (PEC) and dielectric objects can be efficiently simulated using marching-on-in-time (MOT)-based time-domain (TD) integral-equation (IE) : Yang Liu, Eric Michielssen. CEM techniques based on integral equations are advantageous in systems where electromagnetic waves are radiated in open regions. The equations are usually discretized using the method of moments in which an unknown physical quantity is expanded in terms of a set of known expansion functions. This text/reference is a detailed look at the development and use of integral equation methods for electromagnetic analysis, specifically for antennas and radar scattering. Developers and practitioners will appreciate the broad-based approach to understanding and utilizing integral equation methods and the unique coverage of historical developments that led to the current state-of-the-art.
Computational 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). Integral Equations in Electromagnetics Massachusetts Institute of Technology lecturenotes Most integral equations do not have a closed form solution. However, they can often be integral equation is rather minor and infrequent phenomenon, and is therefore often tolerated inpractice. 5. However, there has so far been a lack of suitable literature on time domain computational techniques for solving transient electromagnetic problems via differential and integral equations. Consequently, the motivation for producing on this book arose from the need to fill the existing gap with a text on TD computational techniques that would. Computational electromagnetics is an active research area concerned with the development and implementation of numerical methods and techniques for rigorous solutions to physical problems across the entire spectrum of electromagnetic waves - from radio frequencies to gamma rays. Numerical methods and techniques developed and implemented in this area are now used every day to solve .
Computer Techniques for Electromagnetics discusses the ways in which computer techniques solve practical problems in electromagnetics. It discusses the impact of the emergence of high-speed computers in the study of electromagnetics. This text provides a brief background on the approaches used by mathematical analysts in solving integral equations. Integral Equation Methods for Electromagnetic and Elastic Waves is an outgrowth of several years of work. There have been no recent books on integral equation methods. There are books written on integral equations, but either they have been around for . This book is designed to extend existing literature to the latest development in computational electromagnetic methods, which are of interest to readers in both academic and industrial areas. The topics include advanced techniques in MoM, FEM and FDTD, spectral domain method, GPU and Phi hardware acceleration, metamaterials, frequency and time. Foundations of Applied Electrodynamics takes a fresh look at the essential concepts and methods of electrodynamics as a whole, uniting the most relevant contemporary topics under a common mathematical framework. It contains clear explanations of high-level concepts as well as the mutual relationships between the essential ideas of electromagnetic theory.
