  • Quadratic solitons: recent developments 

    Torner Sabata, Lluís; Barthelemy, A (2003-01)
    Article
    Accés restringit per política de l'editorial
    Multicolor optical solitons mediated by quadratic nonlinearities have been observed experimentally during the last few years in a variety of materials and geometries in a number of laboratories around the world. Today, ...
  • Second harmonic generation, beam dynamics and spatial soliton generation in PPKTP 

    Kim, H; Jankovic, L; Stegeman, G; Carrasco Rodríguez, Sílvia; Torner Sabata, Lluís; Katz, M; Eger, D (2003-03)
    Article
    Accés restringit per política de l'editorial
    Spatial solitons were investigated in periodically poled KTiOPO4 under conditions of second harmonic generation and many new features associated with soliton generation in quasi-phase-matched samples were observed .The ...
  • Soliton molecules: robust clusters of light bullets 

    Crasovan, L C; Kartashov, Yaroslav V.; Milahache, D; Torner Sabata, Lluís; Kivshar, Y; Perezgarcia, V (2003-04)
    Article
    Accés restringit per política de l'editorial
    We show how to generate robust self-sustained clusters of soliton bullets—spatiotemporal (optical or matter-wave) solitons. The clusters carry an orbital angular momentum being supported by competing nonlinearities. The ...
  • Observation of multiple soliton generation mediated by amplification of asymmetries 

    Carrasco Rodríguez, Sílvia; Polyakov, S; Kim, H; Jankovic, L; Stegeman, G I; Pérez Torres, Juan; Torner Sabata, Lluís; Katz, M; Eger, D (2003-04)
    Article
    Accés restringit per política de l'editorial
    We report the experimental observation of the formation of multiple optical quadratic solitons in a process mediated by the amplification of minute asymmetries in the diffraction properties of the input light. Experiments ...
  • Balanced tangential testing for the nonconforming discretization of the Electric-Field Integral Equation on open PeC surfaces 

    Úbeda Farré, Eduard; Sekulic, Ivan; Rius Casals, Juan Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Recent attention has been devoted to the development of nonconforming implementations of the Electric-Field Integral Equation (EFIE), which impose no continuity constraints in the expansion of the current between ...
  • Impact of amplitude calibration errors on SMOS global images 

    Durán Martínez, Israel; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Oliva, Roger; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Some of the artifacts observed in SMOS brightness temperature images are originated in an inconsistency between correlation and antenna temperature calibration errors, which produces a multiplicative bias that scales with ...
  • Mitigation of cross-polar antenna pattern errors in SMOS: simplified approach 

    Durán Martínez, Israel; Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Lin, Wu; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper analyzes a simplified image reconstruction method that exclusively takes into account the dominant antenna pattern terms to model image inversion artifacts and mitigate SMOS polarimetric spatial bias over the ...
  • SMOS salinity retrievals enhancement in coastal areas by joint application of nodal sampling and corrected correlator efficiency 

    González Gambau, V.; Olmedo, Edson; Martinez, J.; Turiel Martínez, Antonio; Durán Martínez, Israel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work is focused on the quality improvement of ESA's SMOS (Soil Moisture and Ocean Salinity) salinity retrievals, paying special attention to coastal regions. Two correction techniques have been applied to enhance the ...
