The latest edition of the foundational guide to advanced electromagnetics. In recent years, metasurfaces--ultrathin surfaces capable of taming electromagnetic waves and generating tailored electromagnetic responses--have emerged as a new and exciting area that promises to expand the applications of electromagnetic technology. Balanis' Advanced Engineering Electromagnetics provides the latest advances and applications in electromagnetic technology, including detailed treatment of metasurfaces, and their potential uses and modifications. The result promises to continue the thorough work of earlier editions and provide a foundational introduction to this critical engineering field. Readers of the third edition of Balanis' Advanced Engineering Electromagnetics will also find, in addition to the contents of the previous two editions: * A new chapter on Metasurfaces and equivalent Artificial Impedance Surfaces * Associated MATLAB computer programs * Associated multicolor Power Point slides for self-study and lecture use * Additional examples and expanded end-of-chapter problems Balanis' Advanced Engineering Electromagnetics is valuable for advanced undergraduate and graduate students in electrical engineering, as well as for engineers and scientists associated with electromagnetic technology.
