Book Synopsis Matériaux artificiels : ingénierie de dispersion des micro-ondes à l'optique by : VANBESIEN Olivier
Download or read book Matériaux artificiels : ingénierie de dispersion des micro-ondes à l'optique written by VANBESIEN Olivier and published by Lavoisier. This book was released on 2012-04-16 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 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.
Book Synopsis Dispositifs de propagation, de filtrage et de rayonnement électromagnétiques basés sur les structures périodiques by : Tahsin Akalin
Download or read book Dispositifs de propagation, de filtrage et de rayonnement électromagnétiques basés sur les structures périodiques written by Tahsin Akalin and published by . This book was released on 2002 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les structures périodiques présentent des propriétés singulières pour réaliser les fonctions principales pour les télécommunications. Dans ce travail, nous nous sommes intéressés aux potentialités de ces structures dans le domaine des hyperfréquences pour le filtrage fréquentiel et spatial conduisant à l'accroissement de la directivité des antennes et également à une nouvelle classe de matériau à indice de réfraction négatif. En ce qui concerne le filtrage, des résultats très intéressants ont été obtenus à partir d'une nouvelle topologie, que nous avons proposée, avec une structuration double face en circuit plaqué. Dans ce domaine, les structurations pseudo-périodiques réalisent de bons compromis en termes de pertes d'insertion en bande passante et de niveau de réjection dans la bande interdite. Des études ont également été menées sur les parties passives incluant le filtre d'un circuit monolithique pour la multiplication de fréquence en gamme millimétrique et submillimétrique. Ces dispositifs utilisant une diode HBV (Heterostructure Barrier Varactor) ont montré des niveaux de puissance élevés sur une large bande de fréquence. L'utilisation d'un superstrat de type PBG (Photonic Band Gap) permet de réaliser des antennes extrêmement directives. Nous avons expliqué ce résultat par une résonance de type cavité Fabry-Pérot. Nous nous sommes également basés sur des analogies avec les superréseaux de semiconducteurs pour établir une relation analytique entre l'angle d'ouverture du lobe principal et le coefficient de qualité. Enfin les structures périodiques permettent d'envisager la réalisation de méta-matériaux à indice de réfraction négatif suivant deux approches distinctes. Nous avons étudié plus en détail celle basée sur des valeurs de permittivité et de perméabilité simultanément négatives pour un fonctionnement dans le domaine des hyperfréquences. Des applications potentielles telles que les diviseurs de puissance sur des méta-matériaux homogènes ont été envisagées.

Book Synopsis Building Wireless Community Networks by : Rob Flickenger
Download or read book Building Wireless Community Networks written by Rob Flickenger and published by "O'Reilly Media, Inc.". This book was released on 2003 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
