Computational Methods for Electromagnetics (0780311221) cover image
Computational Methods for Electromagnetics is an indispensable resource for making efficient and accurate formulations for electromagnetics applications and their numerical treatment. Employing a unified coherent approach that is unmatched in the field, the authors detail both integral and differential equations using the method of moments and finite-element procedures. In addition, readers will gain a thorough understanding of numerical solution procedures.

Topics covered include:

  • Two- and three-dimensional integral equation/method-of-moments formulations
  • Open-region finite-element formulations based on the scalar and vector Helmholtz equations
  • Finite difference time-domain methods
  • Direct and iterative algorithms for the solutions of linear systems
  • Error analysis and the convergence behavior of numerical results
  • Radiation boundary conditions
  • Acceleration methods for periodic Green's functions
  • Vector finite elements
Detail is provided to enable the reader to implement concepts in software and, in addition, a collection of related computer programs are available via the Internet. Computational Methods for Electromagnetics is designed for graduate-level classroom use or self-study, and every chapter includes problems. It will also be of particular interest to engineers working in the aerospace, defense, telecommunications, wireless, electromagnetic compatibility, and electronic packaging industries.
