  • Aperture Averaging of Focused Multi-Gaussian Beams 
    Kamacıoğlu, Canan; Baykal, Yahya; Yazgan, Erdem (Electromagnetics Acad, 2013)
    We investigate the behavior of the power fluctuations of the focused annular and flat-topped beams when a realistic receiver possessing a finite sized aperture is employed in turbulent atmospheric optics links. Employing ...
  • Beams with arbitrary field profiles in turbulence - art. no. 652209 
    Baykal, Yahya (Spie-Int Soc Optical Engineering, 2006)
    Characteristics of optical beam incidences that have arbitrary field profiles are examined when they propagate in the turbulent atmosphere. Arbitrary source field profile is introduced by decomposing the source into ...
  • Effect of beam types on the scintillations: A review 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Cai, Yangjian (Spie-Int Soc Optical Engineering, 2009)
    When different incidences are launched in atmospheric turbulence, it is known that the intensity fluctuations exhibit different characteristics. In this paper we review our work done in the evaluations of the scintillation ...
  • Incoherent sinusoidal-Gaussian and annular beam scintillations 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Cai, Yangjian (Spie-Int Soc Optical Engineering, 2008)
    The scintillation index is evaluated in horizontal turbulent atmospheric optical links for incidences of incoherent cosh-Gaussian (IChG), cos-Gaussian (ICG) and annular (IA) beams. Weak turbulence solution is obtained for ...
  • Intensity fluctuations of partially coherent cos Gaussian and cosh Gaussian beams in atmospheric turbulence 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Çil, Celal Zaim; Cai, Yangjian; Korotkova, Olga (IOP Publishing Ltd, 2011-05)
    On-axis and off-axis scintillation indices of partially coherent collimated cos Gaussian and cosh Gaussian beams are evaluated on their propagation in a weakly turbulent atmosphere. In the coherent limits, our results are ...
  • Minimization effects on scintillations of sinusoidal Gaussian beams in strong turbulence 
    Gerçekçioğlu, Hamza; Baykal, Yahya (IOP Publishing Ltd, 2011-11)
    Minimization effects on the on-axis scintillation index of cos Gaussian (cG) and cosh Gaussian (chG) beams are studied in strong turbulence. In our formulation, the unified solution of the Rytov method, which imposes spatial ...
  • Partially coherent off-axis Gaussian beam scintillations 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Cai, Yangjian (Taylor&Francis Ltd, 2010)
    The scintillation index at the receiver origin is formulated for a partially coherent off-axis Gaussian beam in atmospheric turbulence by employing the extended Huygens-Fresnel principle. Our formula correctly reduces to ...
