Computational Electromagnetics with MATLAB, Fourth Edition [PDF ebook] 

This fourth edition of the text reflects the continuing increase in awareness and use of computational electromagnetics and incorporates advances and refinements made in recent years. Most notable among these are the improvements made to the standard algorithm for the finite-difference time-domain (FDTD) method and treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. It teaches the readers how to pose, numerically analyze, and solve EM problems, to give them the ability to expand their problem-solving skills using a variety of methods, and to prepare them for research in electromagnetism.

• Includes new homework problems in each chapter.
• Each chapter is updated with the current trends in CEM.
• Adds a new appendix on CEM codes, which covers commercial and free codes.
• Provides updated MATLAB code.
