Balanis' Advanced Engineering Electromagnetics (3^rd Ed.)

Balanis' Advanced Engineering Electromagnetics

The latest edition of the foundational guide to advanced electromagnetics

Balanis' third edition of Advanced Engineering Electromagnetics - a global best-seller for over 30 years - covers the advanced knowledge engineers involved in electromagnetics need to know, particularly as the topic relates to the fast-moving, continuously evolving, and rapidly expanding field of wireless communications. The immense interest in wireless communications and the expected increase in wireless communications systems projects (antennas, microwaves and wireless communications) points to an increase in the number of engineers needed to specialize in this field.

Highlights of the 3rd Edition include:

• A new chapter, on Artificial Impedance Surfaces (AIS), contains material on current and advanced EM technologies, including the exciting and fascinating topic of metasurfaces for:

1. Control and broadband RCS reduction using checkerboard designs.
2. Optimization of antenna fundamental parameters, such as: input impedance, directivity, realized gain, amplitude radiation pattern.
3. Leaky-wave antennas using 1-D and 2-D polarization diverse-holographic high impedance metasurfaces for antenna radiation control and optimization.
4. Associated MATLAB programs for the design of checkerboard metasurfaces for RCS reduction, and metasurface printed antennas and holographic L WA for radiation control and optimization.

• Throughout the book, there are:

1. Additional examples, numerous end-of-chapter problems, and PPT notes.
2. Fifty three MATLAB computer programs for computations, graphical visualizations and animations.
3. Nearly 4,500 multicolor PowerPoint slides are available for self-study or lecture use.
