Helps professionals find fast, accurate solutions to their designand analysis problems...

The first and only single-source reference of its kind, this uniquebook offers a comprehensive, in-depth look at the state-of-the-artmethods in high-frequency analysis. A superb working resource forresearchers and designers in a wide range of industries, itincludes detailed demonstrations of how these methods can beapplied to design and analysis problems involving radiation,scattering, antennas on structures, mutual coupling, EMC and EMIstudies, terrain propagation and modeling, and more. It is alsodesigned to function equally well as a textbook for graduate-levelcourses in electromagnetics.
* Exhaustive coverage of the latest HF analysis techniques
* Practical solutions to a plethora of engineering problems
* Numerous case studies and illustrative examples
* Discussions of some of the computer codes currently used toperform high-frequency calculations and their relative merits andlimitations.

Electromagnetic engineers often deal with problems in which thesurfaces of the geometrics being studied do not conform to theeleven coordinate systems in which wave equations are separable. Insuch cases, when exact solutions of wave equations don't apply,approximate methods must suffice.

Among these is the class of high-frequency analytical techniquescovered in this book--methods which lately have proven themselvesto be indispensable to the design and analysis of radar systems,antennas, the interpretation of results in remote sensing, and theassessment of electromagnetic compatibility and electromagneticinterference in computer circuits.

The most comprehensive guide to the subject currently available,High-Frequency Electromagnetic Techniques provides an in-depth lookat the latest methods for high-frequency analysis. Designed to helpprofessionals find fast, accurate solutions to their design andanalysis problems, this valuable working resource features manycase studies and realistic examples which vividly demonstrateexactly how high-frequency techniques can be applied to such areasas:
* Analysis of near and far field patterns of horns and corrugatedconical horns and their design
* Analysis and design of various reflector systems
* Slot antennas and their high-frequency formulations and design
* Antennas on finite bodies and on aircraft
* The estimation of mutual coupling between antennas on structures
* EMC and EMI problems with aircraft antennas and antennas onstructures
* Terrain propagation modeling and the prediction of the effects ofterrain geometry and properties on EM wave propagation
* Ground, sea, and atmospheric clutter modeling and the choice ofradar parameters to obtain clutter reduction in manysituations

Readers will also appreciate the fact that the author has devotedan entire chapter to detailed descriptions of all computer codescurrently used to perform high-frequency calculations, includingcritical evaluations of their relative merits and limitations in avariety of applications, whenever possible.

While it can serve as an excellent graduate-level text for coursesin electromagnetics, High-Frequency Electromagnetic Techniques is,above all, an indispensable working resource for researchers anddesigners in the telecommunications, defense, and computerindustries. It also has an extensive list of references andadditional references which would be helpful to readers for furtherstudy.
