This book describes the characterization of liquid crystal materials at microwave frequencies and the usage of these materials in reconfigurable planar antennas and in their electrical tunable components. It reports for the first time the realization of a two-dimensional electronic beam steering antenna and polarization agile planar antennas with liquid crystal display technology. It gives a detailed description of all the theoretical analyses, modeling and design methods that were involved in the realization of these devices as well as their validation using measurement of demonstrative prototypes. This book also shows that low profile, low cost, high gain, electronic beam steering and polarization agile antennas can be fabricated in larger sizes by using existing automated liquid crystal display manufacturing techniques. The innovative ideas and method described in this work represent a considerable advancement in the field of electronically reconfigurable antennas based on liquid crystal technology and are expected to draw significant interest in the future. Such antennas may become important, for example, in mobile terminals integrated into the body of laptops (in the cover) or of automobiles (in the rooftop), ships or boats, for which flat, low-profile and low-cost antennas are required.

This book is the first ever monograph on nematic liquid crystals for microwaves, millimeter waves and terahertz waves. It presents the first hand independent studies on nematic liquid crystals for microwaves, millimeter waves and terahertz waves. This book opens with an introduction to generic liquid crystals and a retrospective review about nematic liquid crystals in microwaves, millimeter waves and terahertz waves. Attention is then focused on the latest in-house progress on microwave, millimeter wave and terahertz nematic liquid crystals. Synthesis and characterization of novel nematic liquid crystals are first presented, followed by indigenous technologies to manufacture functional nematic liquid crystal devices for microwaves, millimeter waves and terahertz waves. A few self-developed representative advanced functional devices are shown to demonstrate the promising perspective of liquid crystals for not only microwaves, millimeter waves and terahertz waves but also many other non-display applications. The presented studies will attract scientists, engineers and students from various disciplines, such as materials, chemical, electrical, biological, and biomedical engineering. The book is intended for undergraduates, graduates, researchers, professionals and industrial practitioners who are interested in developing novel liquid crystals and further extending liquid crystals beyond display.

Tunable Microwave Metamaterial Structures written by Matthias Maasch and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2016-01-23 with Technology & Engineering categories.
This book presents original findings on tunable microwave metamaterial structures, and describes the theoretical and practical issues involved in the design of metamaterial devices. Special emphasis is given to tunable elements and their advantages in terms of feeding network simplification. Different biasing schemes and feeding network topologies are presented, together with extensive prototype measurements and simulations. The book describes a novel, unique solution for beam steering and beam forming applications, and thus paves the way for the diffusion of new agile communication system components. At the same time, it provides readers with an outstanding and timely review of wave propagation in periodic structures, tunability of metamaterials and the technological constraints that need to be considered in the design of reconfigurable microwave components.
