  • A study of source plane Mathieu beams 
    Eyyuboğlu, Halil T. (Springer, 2008-06)
    We derive the source field expressions of different Mathieu beams. In particular, Mathieu beams consisting of the infinite summations of J-type Bessel functions and their Gaussian counterparts are studied. Mathieu beams ...
  • Propagation aspects of Mathieu-Gaussian beams in turbulence 
    Eyyuboğlu, Halil T. (Springer, 2008-06)
    Based on our recent source plane formulation, the propagation characteristics of Mathieu-Gaussian beams in turbulent atmosphere are investigated. In this connection, the average receiver plane intensity expression is deduced ...
  • 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 ...
  • Propagation properties of anomalous hollow beams in a turbulent atmosphere 
    Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Elsevier Science, 2008-11-01)
    Propagation of circular and elliptical anomalous hollow beams in a turbulent atmosphere is investigated in detail. Based on the extended Huygens-Fresnel integral, analytical formulae for the average irradiance of circular ...
  • Scintillation of astigmatic dark hollow beams in weak atmospheric turbulence 
    Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2008-07)
    The scintillation properties of astigmatic dark hollow beams (DHBs) in weak atmospheric turbulence were investigated in detail. An explicit expression for the on-axis scintillation index of an astigmatic DH13 propagating ...
  • Scintillation properties of dark hollow beams in a weak turbulent atmosphere 
    Chen, Y.; Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Springer, 2008-01)
    The on-axis scintillation index for a circular dark hollow beam (DHB) propagating in a weak turbulent atmosphere is formulated, and the scintillation properties of a DHB are investigated in detail. The scintillation index ...
