  • Asymmetric light transmission by using 2D PT-symmetric photonic nanostructure 

    Turduev, M.; Botey Cumella, Muriel; Herrero Simon, Ramon; Kurt, H.; Staliunas, Kestutis; Giden, I. (Wiley-IEEE Press, 2015)
    Conference report
    Restricted access - publisher's policy
    We propose for the first time a simple realization of a two-dimensional Parity-Time symmetric hexagonal shaped photonic structure composed of honeycomb lattice. The structure has a symmetric periodic modulation of the ...
  • Quantifying sudden changes in dynamical systems using symbolic networks 

    Masoller Alonso, Cristina; Hong, Yanhua; Ayad, Sarah; Gustave, Francois; Barland, Stéphane; Pons Rivero, Antonio Javier; Gómez, Sergio; Arenas, Alex (2015-02-24)
    Article
    Open Access
    We characterize the evolution of a dynamical system by combining two well-known complex systems' tools, namely, symbolic ordinal analysis and networks. From the ordinal representation of a time series we construct a network ...
  • Ultrashort pulse chirp measurement via transverse second-harmonic generation in strontium barium niobate crystal 

    Trull Silvestre, José Francisco; Sola, Ïñigo; Wang, Bingxia; Parra, Albert; Krolikowski, W.; Sheng, Y.; Vilaseca Alavedra, Ramon; Cojocaru, Crina (2015-06-01)
    Article
    Open Access
    Pulse compression in dispersive strontium barium niobate crystal with a random size and distribution of the anti-parallel orientated nonlinear domains is observed via transverse second harmonic generation. The dependence ...
  • Suppression of modulation instability by spatio-temporal modulation 

    Staliunas, Kestutis (2013)
    Conference report
    Restricted access - publisher's policy
    Modulation Instability (MI) is at the basis of spontaneous pattern formation in many nonlinear spatially extended systems in Nature, technologies, and in everyday live. In spite of variety of spatial patterns in different ...

  • Acoustically penetrable sonic crystals based on fluid-like scatterers 

    Cebrecos, A.; Romero García, Vicenç; Pico Vila, Rubén; Sánchez Morcillo, Victor José; Botey Cumella, Muriel; Herrero Simon, Ramon; Cheng, Yu Chieh; Staliunas, Kestutis (2015-01-21)
    Article
    Open Access
    We propose a periodic structure that behaves as a fluid-fluid composite for sound waves, where the building blocks are clusters of rigid scatterers. Such building-blocks are penetrable for acoustic waves, and their properties ...
  • Beam focusing in chirped mirror with a defect 

    Cheng, Yu Chieh; Staliunas, Kestutis (IEEE Press ; Wiley, 2004)
    Conference report
    Restricted access - publisher's policy
    Recently the beam focusing in reflection from chirped dielectric mirror has been proposed and demonstrated, where the negative (anomalous) diffraction is responsible for this flat mirror focusing. For a strong focusing ...
  • Excitation/inhibition patterns in a system of coupled cortical columns 

    Malagarriga Guasch, Daniel; Villa, Alessandro; García Ojalvo, Jordi; Pons Rivero, Antonio Javier (2014)
    Conference report
    Restricted access - publisher's policy
    We study how excitation and inhibition are distributed mesoscopically in small brain regions, by means of a computational model of coupled cortical columns described by neural mass models. Two cortical columns coupled ...
  • Exact detection of direct links in networks of interacting dynamical units 

    Rubido, Nicolas; Marti, Arturo; Bianco-Martinez, Ezequiel; Grebogi, Celso; Baptista, Murilo; Masoller Alonso, Cristina (2014-09)
    Article
    Open Access
    The inference of an underlying network topology from local observations of a complex system composed of interacting units is usually attempted by using statistical similarity measures, such as cross-correlation (CC) and ...
  • Beam focalization by chirped mirrors 

    Cheng, Yu Chieh; Peckus, Martynas; Kicas, Simonas; Trull Silvestre, José Francisco; Cojocaru, Crina; Vilaseca Alavedra, Ramon; Drazdys, Ramutis; Staliunas, Kestutis (Optical Society of American (OSA), 2014)
    Conference report
    Restricted access - confidentiality agreement
    A novel application of chirped dielectric mirrors for narrow beam focalization is proposed and demonstrated numerically and experimentally. Analogy to temporal dispersion compensation by chirped dielectric mirrors is discussed.
