Description

As one of the most powerful simulation techniques for solving engineering boundary-value problems, the finite element method has been widely used for analysis of electromagnetic problems in antennas, radar scattering, RF and microwave engineering, high-speed/high-frequency circuits, wireless communication, electrromagnetic compatibility, photonics, remote sensing, biomedical engineering, and space explorations. The Third Edition of this essential and popular text teaches the finite element method for electromagnetic analysis in a systematic, comprehensive manner. It offers engineers a methodical way to quickly master this very powerful numerical technique for solving practical, often complicated, electromagnetic problems.
