Since the concept was first proposed at the end of the 20th Century, metamaterials have been the subject of much research and discussion throughout the wave community. More than 10 years later, the number of related published articles is increasing significantly. On the one hand, this success can be attributed to dreams of new physical objects which are the consequences of the singular properties of metamaterials. Among them, we can consider the examples of perfect lensing and invisibility cloaking. On other hand, metamaterials also provide new tools for the design of well-known wave functions such as antennas for electromagnetic waves. The goal of this book is to propose an overview of the concept of metamaterials as a perspective on a new practical tool for wave study and engineering. This includes both the electromagnetic spectrum, from microwave to optics, and the field of acoustic waves. Contents 1. Overview of Microwave and Optical Metamaterial Technologies, Didier Lippens. 2. MetaLines: Transmission Line Approach for the Design of Metamaterial Devices, Bruno Sauviac. 3. Metamaterials for Non-Radiative Microwave Functions and Antennas, Divitha Seetharamdoo and Bruno Sauviac. 4. Toward New Prospects for Electromagnetic Compatibility, Divitha Seetharamdoo. 5. Dissipative Loss in Resonant Metamaterials, Philippe Tassin, Thomas Koschny, and Costas M. Soukoulis. 6. Transformation Optics and Antennas, André de Lustrac, Shah Nawaz Burokur and Paul-Henri Tichit. 7.

Download Programmable Elastic Metamaterials for Wave Control and Device Applications Book in PDF, ePub and Kindle
Emerging from electromagnetic waves and fast extending to acoustic and elastic waves, metamaterials that exhibit extraordinary wave control abilities have been gaining soaring attention. Over the past two decades, elastic metamaterials with engineered microstructures have provided a variety of appealing solutions for controlling elastic waves and vibrations. By tailoring their internal microstructures at a subwavelength scale, elastic metamaterials fruitfully distinct themselves from traditional materials or phononic crystals by their striking functions in wave trajectory manipulation, cloaking, nonreciprocal and topological wave control, as well as low-frequency wave/vibration mitigation and absorption.

Download Inverse Design of Metamaterials for Wave Control Book in PDF, ePub and Kindle
Metamaterials are engineered materials, whose spatially periodic arrangement of their constituent materials endows the composite assembly with rather unconventional properties, when macroscopically observed. In the context of the three wave-supporting physics regimes -elastodynamics, acoustics, and electromagnetics- metamaterials present unique opportunities for previously unimaginable user control over the resulting wave behavior. To date, the design of metamaterials is mostly done on an ad hoc basis, relying mostly on one-of-a-kind or incremental physical experiments and forward computational modeling. This dissertation introduces a systematic methodology, rooted in inverse problem theory, for engineering the dispersive properties of periodic media to meet a priori, user-defined, wave control objectives. Both scalar and vector waves are considered. In the developed methodology, the material properties and geometry parameters of the unit cell of the periodic medium become the inversion variables. The inversion is driven by the user-defined wave control objective, constrained by the dispersive characteristics of the unit cell. Though the methodology is flexible enough and can accommodate fairly broad dispersion engineering objectives, here the focus is on band-gaping propagating waves at user-defined frequency ranges. Numerical results in the frequency domain demonstrate that the inversion process yields unit cells that indeed attain the user-defined dispersive behavior. The inverted-for unit cells are then used to build metamaterial assemblies of not only finite periodicity, as opposed to infinite, but of fairly narrow periodicity, and are tested in the time domain against broadband excitations: it is shown that it is possible to attain the desired wave control with sub-wavelength size metamaterial assemblies

Download An Introduction to Metamaterials and Waves in Composites Book in PDF, ePub and Kindle
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 Metamaterial Electromagnetic Wave Absorbers Book in PDF, ePub and Kindle
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.

Download Shock Mitigation and Wave Control Using Elastic Metamaterial Structures Book in PDF, ePub and Kindle
Acoustic/Elastic metamaterials have attracted increased attention in recent times. Metamaterials are defined as special materials that exhibit unusual properties not normally found in normal materials. These unusual properties are derived from the specially designed microstructures rather than the chemical composition of the material. Based on the concept of locally resonant metamaterials, these materials are applied in many applications such as impact wave attenuation, blast wave mitigation and wave control and manipulation due to their flexibility and tailoring properties for various needed applications. In this thesis, we present the development of a dissipative elastic metamaterial with multiple Maxwell-type resonators for dynamic load mitigation. Besides the wave attenuation of dynamic loads, we also investigate the asymmetric transmission of elastic waves which has recently been realized by linear structures. We design and propose different diatomic and triatomic elastic metamaterials to obtain large asymmetric elastic wave transmission in multiple low-frequency bands. All these frequency bands can be theoretically predicted to realize one-way wave propagation along different directions of transmission. All proposed models in this research are analytically investigated and numerically verified by both analytical lattice and continuum models. Also, the dynamic responses of the proposed models are explored and analyzed in time and frequency domains. The effect of damping on the proposed models is also investigated for more practical applications. Lastly, experimental verification is further conducted to observe wave asymmetric transmission bands and transient wave responses in time and frequency domains are also explored.

Download Information Metamaterials Book in PDF, ePub and Kindle
Metamaterials have attracted enormous interests from both physics and engineering communities in the past 20 years, owing to their powerful ability in manipulating electromagnetic waves. However, the functionalities of traditional metamaterials are fixed at the time of fabrication. To control the EM waves dynamically, active components are introduced to the meta-atoms, yielding active metamaterials. Recently, a special kind of active metamaterials, digital coding and programmable metamaterials, are proposed, which can achieve dynamically controllable functionalities using field programmable gate array (FPGA). Most importantly, the digital coding representations of metamaterials set up a bridge between the digital world and physical world, and allow metamaterials to process digital information directly, leading to information metamaterials. In this Element, we review the evolution of information metamaterials, mainly focusing on their basic concepts, design principles, fabrication techniques, experimental measurement and potential applications. Future developments of information metamaterials are also envisioned.
