  • Convergence of general beams into Gaussian intensity profiles after propagation in turbulent atmosphere 
    Eyyuboğlu, Halil T.; Baykal, Yahya; Sermutlu, Emre (Elsevier Science, 2006-09)
    It is shown that a general shaped laser beam will eventually approach a Gaussian average intensity profile after propagation in turbulent atmosphere. In our formulation, source field at the exit plane of the laser is taken ...
  • Correction of amplitude distortions for truncated Bessel beam and SER estimation for 4ASK 
    Eyyuboğlu, Halil T. (Taylor&Francis Ltd., 2016)
    We apply amplitude corrections to a truncated Bessel beam that has propagated through turbulent atmosphere modelled by random phase screens. These corrections are realized via transmitting an unmodulated beam in parallel ...

  • Cosine-Gaussian laser beam intensity in turbulent atmosphere 
    Eyyuboğlu, Halil T.; Baykal, Yahya (Spie-Int Soc Optical Engineering, 2004)
    The effects of turbulent atmosphere on cosine-Gaussian laser beams are examined. To this end, a cosine-Gaussian excitation is taken at the source plane, and subsequently the average intensity profile at the receiver plane ...
  • Cross beam scintillations in non-Kolmogorov medium 
    Baykal, Yahya (Optical Soc Amer, 2014-10)
    For the collimated and focused cross beams, the on-axis scintillation index is evaluated when these beams propagate in weak non-Kolmogorov turbulence. In the limiting cases, our solution correctly reduces to the known ...
  • Crossbeam intensity fluctuations in turbulence 
    Baykal, Yahya (Spie-Soc Photo-Optical Instrumentation Engineers, 2014-05)
    Intensity fluctuations of a crossbeam are evaluated in weak atmospheric turbulence. A crossbeam is defined as two asymmetrical Gaussian beams oriented perpendicular to each other, and one of these beams is wider along the ...
  • Cylindrical-sinc beam 
    Bayraktar, Mert; Başdemir, Hüsnü Deniz (Elsevier GMBH, 2014)
    Propagation of diffracted beams in free space has already been identified. One possible solution is derived from the Helmholtz wave equation and this solution is named as cylindrical-sinc beam. Therefore, cylindrical-sinc ...
  • Decoding of LT-like codes in the absence of degree-one code symbols 
    Abdulkhaleq, Nadhir Ibrahim; Gazi, Orhan (Electronics Communications Research Inst., 2016-10)
    Luby transform (LT) codes were the first practical rateless erasure codes proposed in the literature. The performances of these codes, which are iteratively decoded using belief propagation algorithms, depend on the degree ...
  • Degree of polarization for partially coherent general beams in turbulent atmosphere 
    Eyyuboğlu, Halil T.; Baykal, Yahya; Cai, Yangjian (Springer, 2007-10)
    The degree of polarization is found for optical excitations of cosh-Gaussian, cos-Gaussian and annular-Gaussian beams in a turbulent atmosphere. The related formulation is based on the beam coherence polarization matrix. ...
  • Density functional study of AlBn clusters for n=1-14

    Density functional theory (DFT) B3LYP at 6-311++G(d,p) level is employed to optimize the structures of AlBn (n = 1-14) microclusters. Analysis of the energetic and structural stability of these clusters and their various ...
  • Density functional study of physical and chemical properties of nano size Boron Clusters: B-n (n=13-20) 
    Atış, Murat; Özdoğan, Cem; Güvenç, Büşra (Chinese Physical Soc, 2009-08)
    Boron is an element that has ability to build strong and highly directional bonds with boron itself. As a result, boron atoms form diverse structural motifs, ultimately can yield distinct nano structures, such as planar, ...
