An in-depth treatment of array phenomena and all aspects of phased array analysis and designPhased Array Antennas, Second Edition is a comprehensive reference on the vastly evolving field of array antennas. The Second Edition continues to provide an in-depth evaluation of array phenomena with a new emphasis on developments that have occurred in the field over the past decade. The book offers the same detailed coverage of all practical and theoretical aspects of phased arrays as the first edition, but it now includes: New chapters on array-fed reflector antennas; connected arrays; and reflect arrays and retrodirective arraysBrand-new coverage of artificial magnetic conductors, and Bode matching limitationsA clear explanation of the common misunderstanding of scan element pattern measurement, along with appropriate equationsIn-depth coverage of finite array Gibbsian models, photonic feeding and time delay, waveguide simulators, and beam orthogonalityThe book is complemented with a multitude of original curves and tables that illustrate how particular behaviors were derived from the author's hundreds of programs developed over the past forty years. Additionally, numerous computer design algorithms and numerical tips are included throughout the book to help aid in readers' comprehension. Phased Array Antennas, Second Edition is an ideal resource for antenna design engineers, radar engineers, PCS engineers, and communications engineers, or any professional who works to develop radar and telecommunications systems. It also serves as a valuable textbook for courses in phased array design and theory at the upper-undergraduate and graduate levels.

Now in an completely revised, updated, and enlarged Second Edition, Small Antennas in Portable Devices reviews recent significant theoretical and practical developments in the electrically small antenna area. Examining antenna designs that work as well as those that have limitations, this new edition provides practicing engineers and upper level and graduate students with new information on: work on improving bandwidth using spherical helix dipoles; work on electromagnetically coupled structures; exact derivation of the Q for electrically small antennas for both the TE and TM modes; and a new simplified Q formula.

This is the CD-ROM only version of "Overall Equipment Effectiveness". Written primarily for those responsible for the reliability of equipment and the production operation, this innovative book centers on developing and measuring true Overall Equipment Effectiveness (OEE). The author demonstrates that true OEE correlates with factory output, provides a methodology to link OEE with net profits that can be used by reliability managers to build solid business cases for improvement projects, and draws on his own experience by presenting successful improvement applications in every chapter. Additionally, it will also help practitioners better understand Total Productive Maintenance (TPM) and develop an effective foundation to support Reliability-Centered Maintenance (RCM).It develops a minimum set of definitions, a practice application, including three methods of computation, and reconciliation of OEE and various losses; provides the platform and reasons for maintenance and production to work synergistically; helps to identify the hidden factory that exists within the current system in order to begin leveraging its' potential into real bottom line results; integrates the famous Theory of Constraints aspects into an easy to understand shutdown strategy example; and, contains many practical examples throughout to illustrate techniques and methods in a way everyone can easily understand.
