The first time that such a complete systematic analysis of the
mathematical and numerical techniques related to the orthogonal
methods has been given.

With the explosion of the wireless world, greater emphasis than
ever before is being placed on the effective design of antennas.
Orthogonal Methods for Array Synthesis outlines several
procedures of orthogonal methods suitable for antenna array
synthesis. The book presents a simple approach to the design of
antenna arrays to enable the reader to use the classical Orthogonal
Method for synthesis of linear arrays.

This theory-based book, which includes rapid, effective
solutions to design problems for communications applications and
broadcasting, is amply illustrated with real-world examples and
case studies. Also included in the book is the ORAMA MS
Windows-compatible computer tool, patented by Professor Sahalos and
his team.

* Provides comprehensive coverage of the basic principles of
orthogonal methods including an analytical explanation of the
orthogonal method (OM) and the orthogonal perturbation method
(OP)

* Gives rapid, cost-effective solutions to antenna design
problems for communications applications and broadcasting

* Illustrates all theory with practical applications gleaned from
the author's extensive experience in the field of orthogonal
advanced methods for antennas

Providing a complete guide to the theory and applications of the
Orthogonal Methods, this book is a must-read for antenna engineers
and graduate students of electrical and computer engineering and
physics.
