Influence of oxygen reduction on the structural and electronic properties of electron-doped Sr1−xLaxCuO2 thin films
(Elsevier B.V., 2009)
Single-phase, c-axis oriented, e-doped, Sr1−xLaxCuO2 thin films were epitaxially grown on KTaO3 and DyScO3 substrates by reactive rf sputtering. As-grown films being insulating due to oxygen excess, oxygen reduction is ...
Anomalous lateral beam shift and total absorption due to excitation of surface waves in materials with negative refraction
(EUROPEAN PHYSICAL JOURNAL D, 2006)
We studied electromagnetic beam reflection from layered structures that include materials with negative refraction. Excitation of leaky surface waves leads to the formation of anomalous lateral shifts in the reflected beams ...
Ornithological diagnosis of Ovčarsko-Kablarska Gorge
(Univerzitet Crne Gore-Odsjek za BiologijuRepublički institut za Zaštitu PrirodePrirodnjački muzej Crne GoreUniverzitet Crne Gore-Institut za Biologiju mora, 2004)
Između planinskih masiva Ovčara i Kablara u zapadnoj Srbiji nalazi se klisura, nastala erozivnim radom Zapadne Morave. I pored antropogenih degradacionih procesa, Ovčarsko–Kablarska klisura se i dalje odlikuje velikom ...
Spatiotemporal instabilities of counterpropagating beams in nematic liquid crystals
(Elsevier, 2008)
We investigate the behavior of counterpropagating self-trapped optical beam structures in nematic liquid crystals. We treat numerically a time-dependent model for the beam propagation and the director reorientation in a ...
Self-stabilized spatiotemporal dynamics of dissipative light bullets generated from inputs without spherical symmetry in three-dimensional Ginzburg-Landau systems
(Physical Review A, 2007)
In order to meet experimental conditions, the generation, evolution, and self-stabilization of optical dissipative light bullets from non-spherically-symmetric input pulses is studied. Steady-state solutions of the ...
Extension of the stability criterion for dissipative optical soliton solutions of a two-dimensional Ginzburg-Landau system generated from asymmetric inputs
(IOP PUBLISHING, 2008)
The evolution and stability of dissipative optical spatial solitons generated from an input asymmetric with respect to two transverse coordinates x and y are studied. The variational approach used to investigate steady ...
