Metamaterials

Metamaterials have become one of the most important emerging technologies in the scientific community due to its unusual electromagnetic properties. Consequently, during the last years, a huge deal of efforts has been concentrated in order to design functional components and devices based on metamaterials for many potential applications. The main objective of this book is to present in-depth analysis of the theory, properties, and realizations of novel devices that could be integrated within modern and future communication systems. The book contains 11 chapters written by acknowledged experts, researchers, academics, and microwave engineers, providing comprehensive information and covering a wide range of topics on several aspects of microwaves and optics, including polarization conversion, asymmetric transmission, transmission lines, filters, plasmonic lenses, tunable metamaterials, light manipulation, absorbers, and antennas, among others. This book is suitable for scholars from large scientific domain and therefore given to engineers, scientists, graduates, and other interested professionals as a reference on these artificial materials of tomorrow.

Artificial Materials

This book addresses artificial materials including photonic crystals (PC) and metamaterials (MM). The first part is devoted to design concepts: negative permeability and permittivity for negative refraction, periodic structures, transformation optics. The second part concerns PC and MM in stop band regime: from cavities, guides to high impedance surfaces. Abnormal refraction, less than one and negative, in PC and MM are studied in a third part, addressing super-focusing and cloaking. Applications for telecommunications, lasers and imaging systems are also explored.

  • Publisher: Lavoisier

Ce livre propose une synthèse des recherches - des concepts jusqu'aux applications - sur les matériaux artificiels, incluant les cristaux photoniques et les métamatériaux. Il expose les enjeux de performance et les défis de fabrication (jusqu'à l'échelle du nanomètre) pour l'exploitation des effets d'ultra-réfraction ou de réfraction négative induits par l'ingénierie généralisée ou localisée de la dispersion sur l'ensemble du spectre électromagnétique (des micro-ondes à l'optique en passant par le térahertz et l'infrarouge). Didactique, Matériaux artificiels analyse les possibilités de l'optique de transformation tels que les mirages optiques, les lentilles parfaites, les tapis magiques et les capes d'invisibilité. Présentés comme potentiels précurseurs de nouveaux systèmes de contrôle de la propagation des ondes et/ou d'imagerie pour les domaines des télécommunications, de la biologie ou de la médecine, ils permettent d'identifier les principaux verrous théoriques et technologiques actuels.

The Alex Studies

20 years ago Pepperberg set out to discover whether results of pigeon studies necessarily meant that other birds were incapable of mastering cognitive concepts and the rudiments of referential speech. This is a synthesis of her studies.

When Novels Were Books

A literary scholar explains how eighteenth-century novels were manufactured, sold, bought, owned, collected, and read alongside Protestant religious texts. As the novel developed into a mature genre, it had to distinguish itself from these similar-looking books and become what we now call “literature.” Literary scholars have explained the rise of the Anglophone novel using a range of tools, from Ian Watt’s theories to James Watt’s inventions. Contrary to established narratives, When Novels Were Books reveals that the genre beloved of so many readers today was not born secular, national, middle-class, or female. For the first three centuries of their history, novels came into readers...

Unsustainable Inequalities

A Financial Times Best Book of the Year A hardheaded book that confronts and outlines possible solutions to a seemingly intractable problem: that helping the poor often hurts the environment, and vice versa. Can we fight poverty and inequality while protecting the environment? The challenges are obvious. To rise out of poverty is to consume more resources, almost by definition. And many measures to combat pollution lead to job losses and higher prices that mainly hurt the poor. In Unsustainable Inequalities, economist Lucas Chancel confronts these difficulties head-on, arguing that the goals of social justice and a greener world can be compatible, but that progress requires substantial chang...

Burning the Books

A Wolfson History Prize Finalist A New Statesman Book of the Year A Sunday Times Book of the Year “Timely and authoritative...I enjoyed it immensely.” —Philip Pullman “If you care about books, and if you believe we must all stand up to the destruction of knowledge and cultural heritage, this is a brilliant read—both powerful and prescient.” —Elif Shafak Libraries have been attacked since ancient times but they have been especially threatened in the modern era, through war as well as willful neglect. Burning the Books describes the deliberate destruction of the knowledge safeguarded in libraries from Alexandria to Sarajevo, from smashed Assyrian tablets to the torching of the Li...
