  • Apertured paraxial Bessel beams 
    Umul, Yusuf Ziya (Optical Soc Amer, 2010-03)
    The paraxial Bessel beam is obtained by applying an approximation in the wavenumbers. The scattering of the beams by a circular aperture in an absorbing screen is investigated. The scattered fields are expressed in terms ...
  • Comparison of wave structure functions for intensity profiles 
    Eyyuboğlu, Halil T. (Springer, 2009-03)
    We give a list of available wave structure functions (WSFs) of a spherical wave, simultaneously providing some derivation details. The aim is to assess the impact of these WSFs on intensity profiles of various beams ...
  • 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 ...
  • 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. ...
  • Radius of curvature variations for annular, dark hollow and flat topped beams in turbulence 
    Eyyuboğlu, Halil T.; Baykal, Yahya; Ji, X.L. (Springer, 2010-06)
    For propagation in turbulent atmosphere, the radius of curvature variations for annular, dark hollow and flat topped beams are examined under a single formulation. Our results show that for collimated beams, when examined ...
