Numerical Analysis for Electromagnetic Integral Equations (Artech House Electromagnetic Analysis) by Karl F Warnick (PDF)

Description

Numerical simulation is essential to electrical engineers working in antenna design, wireless communications, optical systems, and a host of other areas. This new applications-focused book provides engineers with state-of-the-art methods for predicting simulation accuracy, worked-out results for dozens of real-world problems, the latest accuracy-improving techniques, and detailed guidance for all parameters required to optimize numerical simulations. Bridging the gap between abstract academic treatments and practical engineering needs, this timely work introduces various surface integral equation formulations, approaches to discretizing the integral equations, and measures of solution accuracy. All told, this definitive resource is indispensable for all engineers and software developers working with computational simulation tools in electromagnetics and wave propagation.

⭐Well written.

⭐The book mainly deals with error analysis of the Method of Moments as applied to electromagnetic scattering problems.With particular reference to the case of a perfeclty conducting circular cylinder, the Author provides a very deep explanation of the sources of errors in terms of projection and aliasing errors for the EFIE, MFIE and CFIE and TE/TM incidence. It clarifies, with analytical details, how the smoothness of the kernel of the involved integral equations and the features of the chosen basis/test functions affect the error behavior versus the discretization density and the ill-conditioning of the achieved linear system of equations to be inverted. A generalization to perfectly flat strip/2D wedges and perfectly conducting 3D scatterers is also provided.The cases of resonant structures as well as the use of higher-order basis functions (polynomials) and iterative solutions to linear system of equations are also sketched.The book, which is devoted to people with some background on the Method of Moments already available, is worth to be bought and interesting to be read. The title is a bit misleading: I would have used “error analysis” instead of “numerical analysis”.
