Manipulating light at distance by a metasurface using momentum transformation

A momentum conservation approach is introduced to manipulate light at distance using metasurfaces. Given a specified field existing on one side of the metasurface and specified desired field transmitted from the opposite side, a general momentum boundary condition is established, which determines the amplitude, phase and polarization transformation to be induced by the metasurface. This approach, named momentum transformation, enables a systematic way to synthesize metasurfaces with complete control over the reflected and transmitted fields. Several synthesis illustrative examples are provided: a vortex hypergeometric-Gaussian beam and a "delayed-start" accelerated beam for Fresnel region manipulation, and a pencil beam radiator and a holographic repeater for Frauenhofer region manipulation

One Numerical Complex Analysis Method for Parameters Identification of Piecewise Homogeneous Conductivity Media with Using Applied Quasipotential Tomographic Data

We propose one approach for gradient problems solving of parameters identification in piecewise homogeneous fields based on numerical complex analysis method with using applied quasipotential tomographic dat

The Abelian/Nonabelian Correspondence and Frobenius Manifolds

We propose an approach via Frobenius manifolds to the study (began in math.AG/0407254) of the relation between rational Gromov-Witten invariants of nonabelian quotients X//G and those of the corresponding ``abelianized'' quotients X//T, for T a maximal torus in G. The ensuing conjecture expresses the Gromov-Witten potential of X//G in terms of the potential of X//T. We prove this conjecture when the nonabelian quotients are partial flag manifolds.Comment: 35 pages, no figure

Kratak kronološki pregled kartiranja teritorija Bosne i Hercegovine

The territory of today\u27s Bosnia and Herzegovina has historically been part of the various empires or communist states of the Socialist Federal Republic of Yugoslavia. Very little research in the fild of cartography related to the historical account of the teritory of Bosnia and Herzegovina has been done. However, recently more and more attention is paid to this topic. The article was created on the basis of an independent long-term research by the author, and was motivated by the lack of literature in this field. Teherefore, this text will give a brief overview of the development of cartography until 1992, when the war in Bosnia and Herzegovin begun. It will also show the historical timeline of representing the territory of Bosnia and Herzegovina on maps.Teritorij današnje Bosne i Hercegovine, povijesno gledano, bio je dio raznih imperija, kao i komunističke države Socijalističke Federativne Republike Jugoslavije. Postoji vrlo malo istraživanja vezano za kartografski prikaz teritorija Bosne i Hercegovine kroz povijest. Međutim, nedavno se sve više pažnje posvećuje toj temi. Članak je izrađen na temelju neovisnog dugogodišnjeg istraživanja autorice, koja je bila motivirana nedostatkom literature u tom području. Stoga će se u radu dati kratak pregled kartografije ovog područja do 1992. godine, kada je započeo rat u Bosni i Hercegovini. Također, prikazat će se povijesna vremenska linija vizualiziranja teritorija Bosne i Hercegovine na kartama
