Book Synopsis An Introduction to Metamaterials and Waves in Composites by : Biswajit Banerjee
Download or read book An Introduction to Metamaterials and Waves in Composites written by Biswajit Banerjee and published by CRC Press. This book was released on 2011-06-07 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Requiring no advanced knowledge of wave propagation, An Introduction to Metamaterials and Waves in Composites focuses on theoretical aspects of metamaterials, periodic composites, and layered composites. The book gives novices a platform from which they can start exploring the subject in more detail. After introducing concepts related to elasticity, acoustics, and electrodynamics in media, the text presents plane wave solutions to the equations that describe elastic, acoustic, and electromagnetic waves. It examines the plane wave expansion of sources as well as scattering from curved interfaces, specifically spheres and cylinders. The author then covers electrodynamic, acoustic, and elastodynamic metamaterials. He also describes examples of transformations, aspects of acoustic cloaking, and applications of pentamode materials to acoustic cloaking. With a focus on periodic composites, the text uses the Bloch-Floquet theorem to find the effective behavior of composites in the quasistatic limit, presents the quasistatic equations of elastodynamic and electromagnetic waves, and investigates Brillouin zones and band gaps in periodic structures. The final chapter discusses wave propagation in smoothly varying layered media, anisotropic density of a periodic layered medium, and quasistatic homogenization of laminates. This book provides a launch pad for research into elastic and acoustic metamaterials. Many of the ideas presented have yet to be realized experimentally—the book encourages readers to explore these ideas and bring them to technological maturity.

Download or read book Metamaterials and Their Applications written by Dharani Sabba and published by Arcler Press. This book was released on 2017-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial materials such as metamaterials are gaining interest in research area in recent years owing to their extraordinary properties as implied by the word "Meta" meaning "beyond" in Greek. These metamaterials constitute periodic or nonperiodic subwavelength macro cells which exhibit properties based on the design of the macro units resulting in special materials that do not exist in nature. Though the metamaterials have achieved significant breakthroughs in theory, application of these materials requires considerable progress. Some recent advances in terms of their application comprise of revolutionary electronics, filtering of sound and light, biosensors, absorbers of electromagnetic radiation, antennas with improved performance, invisible submarines etc. These metamaterials are classified into electromagnetic (EM), chiral, tetrahertz, photonic metamaterials, tunable metamaterials with the ability to modify the frequency of refractive index, frequency selective surfaces and nonlinear metamaterials. EMs are chiefly used for optical and microwave applications such as band-pass filters, lenses, microwave couplers, antenna radomes, etc. Some of the salient characteristics of these materials are their ability to control the direction of electromagnetic radiation, achieve enhanced bandwidth and radiated power and reduce the beam-width and return loss in contrast to the conventional antennas.As the field of metamaterials is interesting and has potential for next generation applications, in this book, a compilation of research articles and reviews showcasing the synthesis, properties, numerical models and the application of these metamaterials in various fields has been illustrated. Chapters 1-6 are compilation of research and invited articles manifesting the various synthesis routes of metamaterials with chapters 4-6 focusing on the theoretical models used for the fabrication of these materials while chapters 7-9 highlight the properties of the metamaterials. The final chapters 10-17 acquaint the reader with the numerous applications of the metamaterials such as lens, absorber materials, sensors, antennas, etc. Chapter 11 is a review on the theory and application of tunable metamaterials. As this book comprises of research articles ranging from synthesis to numerical modeling of metamaterials, it will appeal to audience with strong inclination towards physics, computer simulations, material science and electronics. Also as these metamaterials are important in many defense applications, the reader will find this book compelling to research extensively and adopt these materials into advanced technologies for the safety and progress of one's nation.
Book Synopsis Electromagnetic Metamaterials by : Christophe Caloz
Download or read book Electromagnetic Metamaterials written by Christophe Caloz and published by John Wiley & Sons. This book was released on 2005-11-22 with total page 352 pages. 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.

This book was released on 2020-02-14 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the proceedings of the 4th International Conference on Internet of Things and Connected Technologies (ICIoTCT), held on May 9–10, 2019, at Malaviya National Institute of Technology (MNIT), Jaipur, India. The Internet of Things (IoT) promises to usher in a revolutionary, fully interconnected “smart” world, with relationships between objects and their environment and objects and people becoming more tightly intertwined. The prospect of the Internet of Things as a ubiquitous array of devices bound to the Internet could fundamentally change how people think about what it means to be “online”. The ICIotCT 2019 conference provided a platform to discuss advances in Internet of Things (IoT) and connected technologies, such as various protocols and standards. It also offered participants the opportunity to interact with experts through keynote talks, paper presentations and discussions, and as such stimulated research. With the recent adoption of a variety of enabling wireless communication technologies, like RFID tags, BLE, ZigBee, embedded sensor and actuator nodes, and various protocols such as CoAP, MQTT and DNS, IoT has moved on from its infancy. Today smart sensors can collaborate directly with machines to automate decision-making or to control a task without human involvement. Further, smart technologies, including green electronics, green radios, fuzzy neural approaches, and intelligent signal processing techniques play an important role in the development of the wearable healthcare devices.
Book Synopsis Metamaterial Electromagnetic Wave Absorbers by : Willie J. Padilla
Download or read book Metamaterial Electromagnetic Wave Absorbers written by Willie J. Padilla and published by Morgan & Claypool Publishers. This book was released on 2022-01-24 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic metamaterials are a family of shaped periodic materials which achieve extraordinary scattering properties that are difficult or impossible to achieve with naturally occurring materials. This book focuses on one such feature of electromagnetic metamaterials—the theory, properties, and applications of the absorption of electromagnetic radiation. We have written this book for undergraduate and graduate students, researchers, and practitioners, covering the background and tools necessary to engage in the research and practice of metamaterial electromagnetic wave absorbers in various fundamental and applied settings. Given the growing impact of climate change, the call for innovations that can circumvent the use of conventional energy sources will be increasingly important. As we highlight in Chapter 6, the absorption of radiation with electromagnetic metamaterials has been used for energy harvesting and energy generation, and will help to reduce reliance on fossil fuels. Other applications ranging from biochemical sensing to imaging are also covered. We hope this book equips interested readers with the tools necessary to successfully engage in applied metamaterials research for clean, sustainable energy. This book consists of six chapters. Chapter 1 provides an introduction and a brief history of electromagnetic wave absorbers; Chapter 2 focuses on several theories of perfect absorbers; Chapter 3 discusses the scattering properties achievable with metamaterial absorbers; Chapter 4 provides significant detail on the fabricational processes; Chapter 5 discusses examples of dynamical absorbers; and Chapter 6 highlights applications of metamaterial absorbers.
Book Synopsis Hyperbolic Metamaterials by : Igor I Smolyaninov
Download or read book Hyperbolic Metamaterials written by Igor I Smolyaninov and published by Morgan & Claypool Publishers. This book was released on 2018-03-23 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperbolic metamaterials were originally introduced to overcome the diffraction limit of optical imaging. Soon thereafter it was realized that hyperbolic metamaterials demonstrate a number of novel phenomena resulting from the broadband singular behavior of their density of photonic states. These novel phenomena and applications include super resolution imaging, new stealth technologies, enhanced quantum-electrodynamic effects, thermal hyperconductivity, superconductivity, and interesting gravitation theory analogs. Here I review typical material systems, which exhibit hyperbolic behavior and outline important new applications of hyperbolic metamaterials, such as imaging experiments with plasmonic hyperbolic metamaterials and novel VCSEL geometries, in which the Bragg mirrors may be engineered in such a way that they exhibit hyperbolic properties in the long wavelength infrared range, so that they may be used to efficiently remove excess heat from the laser cavity. I will also discuss potential applications of self-assembled photonic hypercrystals. This system bypasses 3D nanofabrication issues, which typically limit hyperbolic metamaterial applications. Photonic hypercrystals combine the most interesting features of hyperbolic metamaterials and photonic crystals.
Book Synopsis Vision and Voyages for Planetary Science in the Decade 2013-2022 by : National Research Council
Download or read book Vision and Voyages for Planetary Science in the Decade 2013-2022 written by National Research Council and published by National Academies Press. This book was released on 2012-01-30 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.
