  • 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 ...
  • Bit error rates for focused general-type beams 
    Altay Arpalı, Serap; Baykal, Yahya (Electromagnetics Acad, 2009)
    Using the scintillation index of general beam formulation, bit error rate (BER) is investigated for focused Gaussian, cos-Gaussian, cosh-Gaussian and annular beams in weak atmospheric turbulence. We have employed our ...
  • Comment On 'Fringe Waves in An Impedance Half-Plane' 
    Başdemir, Hüsnü Deniz (Electromagnetics Acad, 2014)
  • Diffraction properties of partially coherent elegant high-order beam 
    Wang, Fei; Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Electromagnetics Acad, 2010)
    The diffraction properties of a partially coherent elegant higher-order beam in free space are investigated in detail. It is found that the diffraction properties of a partially coherent elegant higher-order beam upon ...
  • Effects of Focusing on Scintillations of Higher Order Laser Modes in Non-Kolmogorov Turbulence 
    Baykal, Yahya (Electromagnetics Acad, 2014)
    The scintillation index of focused higher order laser beam propagating in non-Kolmogorov atmospheric turbulence is formulated by employing the Rytov method and the equivalence of the structure constant. Our evaluations are ...
  • Flat-Topped Field Correlations In Extremely Strong Turbulence 
    Baykal, Yahya (Electromagnetics Acad, 2011)
    In extremely strong turbulent horizontal atmospheric optical links, field correlations of flat-topped Gaussian incidence are evaluated. Field correlations are represented versus the diagonal distance at the receiver plane, ...
  • Formulation of scintillations for optical incidence of arbitrary field profile 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Cai, Yangjian (Electromagnetics Acad, 2008)
    Scintillation index on the receiver axis is formulated in random medium when an optical source with an arbitrary field profile is employed. To represent the arbitrary source field profile, source is decomposed into pixels ...
  • Propagation of partially coherent beams after a source plane ring aperture 
    Eyyuboğlu, Halil T.; Baykal, Yahya; Cai, Y. (Electromagnetics Acad, 2008)
    The propagation properties of partially coherent beams passing through a source placed ring aperture are examined. The derivation is based on the lowest order general beam formulation, such that our results are applicable ...
  • Scintillations in weak turbulence of annular beams whose individual components are incoherent 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Cai, Y. (Electromagnetics Acad, 2010-03-22)
    The scintillation index, arising from the intensity fluctuations in weak atmospheric turbulence of annular beams whose individual components are incoherent, is formulated. For such beams whose annularities are obtained by ...
