Sommario/riassunto |

The topic of guided wave (GW) propagation comprises a vast research area overlapping with photonics, matter waves in macroscopic quantum media (ultracold gases of bosonic and fermionic atoms, condensates of quasiparticles, such as excitons-polaritons, magnons, and cavity photons), hydrodynamics, acoustics, plasma physics, etc. In many situations, tightly confined GWs naturally acquire high amplitudes, which gives rise to a plenty of fascinating nonlinear effects. In particular, waveguides often provide a combination of nonlinearity, group-velocity dispersion, and low losses which is necessary for the creation of solitons (robust solitary waves). In optics, experimental and theoretical work with GWs is a vast research area, with great significance both for fundamental studies and numerous applications, which are realized in linear and nonlinear forms alike, including long-haul telecommunications, all-optical data-processing schemes, and generation of powerful laser beams, especially in fiber lasers. More recently, new artificially created optical media have been made available, such as photonic crystals, metamaterials, photonic topological insulators, PT-symmetric waveguides, and others, which opens a way to implement GW propagation regimes with features that were not known previously - e.g., the propagation immune to scattering on defects, or light diodes, admitting strictly unidirectional transmission. Closely related to optical waveguides are their plasmonic counterparts, which admit the implementation of the GW transmission on much smaller scales, by using surface-plasmon-polaritonic waves with small wavelengths. Completely new perspectives for the exploration and application of GWs emerge in the area of |

Après une quinzaine d’années de reconstruction dans un climat de paix relative, de 1990 à 2004, le Liban a connu depuis 2005 une succession d’épisodes politiques violents mêlant de manière complexe enjeux internes et tensions régionales. Le déclenchement de la crise syrienne et ses retombées politiques, économiques et démographiques sur le |

Liban accentue cet état de fait. Cet ouvrage met en lumière ces nouveaux défis et complète en intégrant des volets différents l’analyse des transformations libanaises déjà entreprises dans l’Atlas du Liban. Territoires et société publié en 2007 par la même équipe. Outre la crise internationale et les mouvements de population, il prend en compte les dimensions socio-économiques à l’intérieur du Liban, les problématiques environnementales liées à l’urbanisation incontrôlée et aux risques, ainsi que la gestion territoriale et les conflits locaux qu’elle suscite. Cet atlas est le fruit d’une collaboration entre des chercheurs et universitaires français et libanais. Il utilise une approche géographique, plaçant au premier plan de l’analyse la spatialisation des faits sociaux et naturels. Les sources publiques sont limitées, notamment du point de vue de la finesse géographique, parfois peu fiables et difficiles d’accès. C’est particulièrement vrai pour les données sur la population libanaise, moins bien connue que la population réfugiée. Les données internationales permettent de situer le Liban par rapport à ses voisins. Des données thématiques, issues des ministères, offrent néanmoins une vision détaillée pour certains domaines. L’analyse d’images aériennes et de satellites fournit des données essentielles sur l’urbanisation et l’environnement. Des enquêtes de terrain localisées et thématiques complètent la panoplie des informations utilisées. L’ouvrage comprend six chapitres. Le premier porte sur la géopolitique régionale, les violences politiques internes et leurs effets locaux, à savoir l’installation des réfugiés syriens et la… |
