Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic metamaterials-from fundamental physics to advanced engineering applications This book presents an original generalized transmission line approach associated with non-resonant structures that exhibit larger bandwidths, lower loss, and higher design flexibility. It is based on the novel concept of composite right/left-handed (CRLH) transmission line metamaterials (MMs), which has led to the development of novel guided-wave, radiated-wave, and refracted-wave devices and structures. The authors introduced this powerful new concept and are therefore able to offer readers deep insight into the fundamental physics needed to fully grasp the technology. Moreover, they provide a host of practical engineering applications. The book begins with an introductory chapter that places resonant type and transmission line metamaterials in historical perspective. The next six chapters give readers a solid foundation in the fundamentals and practical applications: Fundamentals of LH MMs describes the fundamental physics and exotic properties of left-handed metamaterials TL Theory of MMs establishes the foundations of CRLH structures in three progressive steps: ideal transmission line, LC network, and real distributed structure Two-Dimensional MMs develops both a transmission matrix method and a transmission line method to address the problem of finite-size 2D metamaterials excited by arbitrary sources Guided-Wave Applications and Radiated-Wave Applications present a number of groundbreaking applications developed by the authors The Future of MMs sets forth an expert view on future challenges and prospects This engineering approach to metamaterials paves the way for a new generation of microwave and photonic devices and structures. It is recommended for electrical engineers, as well as physicists and optical engineers, with an interest in practical negative refractive index structures and materials.

Book excerpt: Transformation electromagnetics is a systematic design technique for optical and electromagnetic devices that enables novel wave-material interaction properties. The associated metamaterials technology for designing and realizing optical and electromagnetic devices can control the behavior of light and electromagnetic waves in ways that have not been conventionally possible. The technique is credited with numerous novel device designs, most notably the invisibility cloaks, perfect lenses and a host of other remarkable devices. Transformation Electromagnetics and Metamaterials: Fundamental Principles and Applications presents a comprehensive treatment of the rapidly growing area of transformation electromagnetics and related metamaterial technology with contributions on the subject provided by a collection of leading experts from around the world. On the theoretical side, the following questions will be addressed: “Where does transformation electromagnetics come from?,” “What are the general material properties for different classes of coordinate transformations?,” “What are the limitations and challenges of device realizations?,” and “What theoretical tools are available to make the coordinate transformation-based designs more amenable to fabrication using currently available techniques?” The comprehensive theoretical treatment will be complemented by device designs and/or realizations in various frequency regimes and applications including acoustic, radio frequency, terahertz, infrared, and the visible spectrum. The applications encompass invisibility cloaks, gradient-index lenses in the microwave and optical regimes, negative-index superlenses for sub-wavelength resolution focusing, flat lenses that produce highly collimated beams from an embedded antenna or optical source, beam concentrators, polarization rotators and splitters, perfect electromagnetic absorbers, and many others. This book will serve as the authoritative reference for students and researchers alike to the fast-evolving and exciting research area of transformation electromagnetics/optics, its application to the design of revolutionary new devices, and their associated metamaterial realizations.
Download or read book Theory and Applications of a Uniplanar Transmission line Metamaterial inspired Electromagnetic Bandgap Structure written by Stuart E. Barth and published by . This book was released on 2015 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multitude of planar electromagnetic bandgap structures (EBGs) have been proposed for the suppression of parallel-plate waveguide (PPW) and surface-wave (SW) modes at microwave frequencies. Some of these structures have been well-modelled with transmission-line theory, however, these structures typically employ vias which prevent these structures from being used at high frequencies or in low-cost applications, where vias can be difficult or expensive to manufacture. Alternatively, EBGs have been proposed which overcome this limitation with a uniplanar design, such that they are simple to manufacture using standard lithographic processes. However, these structures generally suffer from the lack of a rigorous model, such that the bandgap properties are difficult to control without changing the overall size of the EBG. This work seeks to overcome this limitation through the development of a uniplanar EBG structure which is shown to be well-described by a proposed multiconductor transmission-line model. Transmission-line metamaterial techniques are then used to miniaturize the EBG's constituent unit cells, without any loss of model accuracy. Although this EBG is inherently one-dimensional, it is shown that it can be arranged radially to effect suppression in two dimensions. The EBG is created by loading the coplanar waveguide (CPW) conductors of a shielded, conductor-backed CPW (S-CBCPW) structure with series capacitors and shunt inductors, as inspired by transmission-line metamaterials. The bandgaps used in this work are shown to arise through modal coupling, in which the loaded CPW mode couples with the PPW and/or SW modes to prevent the transmission of power. To demonstrate the effectiveness and versatility of this EBG, it is applied to two applications: the suppression of parallel-plate noise between two vias at X-band, and the suppression of the SW mode on a GPS antenna ground plane at L-band. It is shown that the full-wave simulated results agree well with the periodic analysis of the equivalent-circuit model developed in this work. Finally, the designed EBGs were manufactured and tested to verify these results. Several avenues of further study and applications are suggested.

Download or read book Metamaterial inspired Structures for Microwave and Terahertz Applications written by Amir Ebrahimi and published by . This book was released on 2016 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic metamaterials are engineered materials that exhibit controllable electromagnetic properties within a desired frequency range. They are usually made of periodic metallic resonant inclusions with dimensions much smaller than the operational wavelength. Since their introduction, they have found many applications from the microwave frequency range up to the terahertz and optical ranges. One key advantage of metamaterial lies in their sub-wavelength resonators making them suitable for miniaturisation of RF circuits and components. This thesis investigates applications of metamaterial-inspired resonators and structures to design improved devices and components operating at either the microwave or terahertz frequency range. The first part of the dissertation is on the design of miniaturised microwave filters for integrated portable RF systems. Dual-mode metamaterial resonators are proposed as alternatives to conventional resonators for size reduction of the RF filters. In the second part, the focus is on the design of compact metamaterial sensors with improved functionalities. Complementary metamaterial resonators are proposed for designing microfluidic sensors with improved sensitivity and linearity. The designed microfluidic sensors have been tested and verified for dielectric characterisation of chemical and biological solutions. A wide dynamic-range displacement sensor has been designed based on a microstrip-line-coupled complementary electric- LC (ELC) resonator. Furthermore, a rotation sensor is designed with coupled U-shaped resonator with a dynamic range of 180°, where the sensor linearity is improved by asymmetrically tapering the resonators shape. The third part focuses on the design of microwave and terahertz frequency selective surfaces (FSS) based on metamaterial miniaturised elements. Tunable and dual-band FSSs are proposed for reconfigurable and multi-standard microwave communications. Eventually, miniaturised-elements are used to design second-order FSSs at the terahertz frequency range. The simulation and measurement results confirm a harmonic-free and stable frequency response of the designed FSSs under oblique incidence angles. Overall, the research outcomes in this thesis suggest the efficiency of metamaterial resonators for the design of sensing and communications devices with improved performance over a wide frequency range from the microwave up to terahertz.
