CAD of Microstrip Antennas for Wireless Applications (Artech House Antennas and Propagation Library) By Robert A. Sainati Publisher: Artech House Number Of Pages: 255 Publication Date: 1996-01-15 ISBN-10 / ASIN: 0890065624 ISBN-13 / EAN: 9780890065624 Binding: Hardcover Summary: straight out of the J.Peterman catalog.... Rating: 5 "Oh, I'm exhausted. I've been on this street a thousand times. It's never looked so strange. The faces...so cold. In the distance a child is crying...fatherless...a bastard child, perhaps. My back aches, my heart aches, but my eyes...my eyes are resilient! Thank God I put on my reading glasses and started my CAD of Microstrip Antennas for Wireless Applications!....To think, I wasn't going to take this out of the lab..but I knew deep down inside that the toll road of denial is a long and dangerous one. The price? My soul." Summary: Electrifying Read! Rating: 5 As I was sitting in my cage the other night, I felt a magnetic attraction to this book. I particularly enjoyed how the fields were interweaved throughout the text. Near fields, far fields, clover fields, corn fields. This one has it all! Summary: Brilliant grasp of my equations! Rating: 5 The author truly has mastered my equations and displays practical application of them to real world situations. Once I started reading, I couldn't put it down! Field calculations and microstrip design can sometimes be a little dry, but the author makes it not only interesting, but fun as well. I would like to see him branch out into solving world peace and time travel next, as he seems well equipped to tackle those subjects after this etraordinary work. I wish I could give 6 stars. Summary: almost useless Rating: 1 As a designer of planar antennae I found this book to be of very little use. Designing anything more complex than a directly fed patch radiator with this book in hand, such as an EMC patch radiator or a slot-coupled one, amounts to: 1) getting very approximate numbers to say the least, running the little computer program which is provided with the book, or using the formulae from the latter, 2) patiently sliding substrate layers on top of each other while keeping a hopeful eye on the network analyser, 3) performing a lot of scalpel work; fine for GPS, a nightmare at X-band or above... I have used decent models which have been published elsewhere in the technical litterature, for designing the aforementioned radiators, with good results. In fact Artech House, the original publisher do not even advertise this book any more!

Alignment Technologies and Applications of Liquid Crystals By Kohki Takatoh, Masanori Sakamoto, Ray Hasegawa, Mitsushiro Koden, Nobuyuki Itoh, Masaki Hasegawa Publisher: CRC Number Of Pages: 320 Publication Date: ISBN-10 / ASIN: 0748409025 ISBN-13 / EAN: 9780748409020 Binding: Hardcover Book Description: Alignment phenomena are characteristic of liquid crystalline materials, and understanding them is critically important in understanding the essential features and behavior of liquid crystals and the performance of Liquid Crystal Devices (LCDs). Furthermore, in LCD production lines, the alignment process is of practical importance. Alignment Technologies and Applications of Liquid Crystal Devices demonstrates both the fundamental and practical aspects of alignment phenomena in liquid crystals. The physical basis of alignment phenomena is first introduced in order to aid the understanding of the various physical phenomena observed in the interface between liquid crystalline materials and alignment layer surfaces. Methods for the characterization of surfaces, which induce the alignment phenomena, and of the alignment layer itself are introduced. These methods are useful for the research of liquid crystalline materials and devices in academic research as well as in industry. In the practical sections, the alignment methods used in the LCD production lines are introduced with various other trials for the alignment technologies. LCD performances are also discussed in relation to alignment phenomena. The authors have a wide range of experience in both academic research and in industry. This book will be of interest to researchers and engineers working in the LCD industry, and for physics and chemistry researchers studying liquid crystalline materials.

Contrary to some opinions, electric motors are decidedly not part of an old-fashioned area of research. They are, in fact, the most popular machines of everyday life, and the number of types increase almost every year. Advances in materials engineering, power electronics, and control strategies along with energy and reliability demands continue to stimulate the development of exciting new technologies and applications. Ranking high among the most exciting of these technologies are linear synchronous motors (LSMs). Linear Synchronous Motors: Transportation and Automation Systems provides a comprehensive treatment of all types of brushless LSMs-their construction, electromagnetic effects, control, and applications. It explains the physics of hard magnetic materials, discusses permanent magnet and superconducting excitation systems, and addresses applications in factory automation and high-speed transportation systems.LSMs have better performance and higher power density than their induction counterparts, and they can operate with a larger mechanical clearance between their stationary and moving parts. Paying equal attention to the design and the applications of LSMs, Linear Synchronous Motors offers a unique opportunity to master the inner workings of LSMs, discover new research results, and keep abreast of their emerging applications. Electromechanical designers, electrical and mechanical engineers, as well as linear motor enthusiasts will welcome this broad and authoritative work to their reference collections.

Practical Design Control Implementation for Medical Devices By Jose Justiniano, Venky Gopalaswamy Publisher: Informa HealthCare Number Of Pages: 232 Publication Date: 2003-03-12 ISBN-10 / ASIN: 1574911279 ISBN-13 / EAN: 9781574911275 Binding: Hardcover Product Description: Bringing together, for the first time, the concepts of design control and reliability engineering, Practical Design Control Implementation helps you face the challenge of designing and developing products that comply with regulatory requirements and fulfill customer expectations. Written with all levels of management and technical personnel in mind, the authors demonstrate how successful design control implementation can result in fewer customer complaints and medical device reports, more satisfied customers, and faster time-to-market. Part One focuses on the practical aspects of design control implementation for medical devices. The fundamental concepts of design control are not new. What is new is the adoption by the FDA of these principles and their consequent enforcement. Also new to the medical device industry are the different technical concepts, tools, and techniques necessary to implement design control. In this section, each chapter provides practical advice and insight on the required FDA design control elements. Part Two explores the reliability of medical devices and how design control can influence that reliability. The book presents easy to understand examples of typical product design and development phases with the corresponding reliability and risk analysis tools such as failure modes and effects analysis (FMEA), hazard analysis, reliability planning, reliability prediction, design verification, and validation. The authors discuss the inter-relatedness of reliability engineering and design control and apply the concept to medical device design. Providing common sense explanations and guidance, Practical Design Control Implementation helps readers successfully execute design control and reliability engineering procedures that not only meet the FDA guidelines but also meet or exceed customer expectations.
