  • Average irradiance and polarization properties of a radially or azimuthally polarized beam in a turbulent atmosphere 
    Cai, Yangjian; Qiang, Lin; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Society of America, 2008-05-26)
    Analytical formulas are derived for the average irradiance and the degree of polarization of a radially or azimuthally polarized doughnut beam (PDB) propagating in a turbulent atmosphere by adopting a beam coherence-polarization ...
  • Flat topped beams and their characteristics in turbulent media 
    Eyyuboğlu, Halil T.; Arpalı, Çağlar; Baykal, Yahya (Optical Society of America, 2006-05)
    The source and receiver plane characteristics of flat topped (FT) beam propagating in turbulent atmosphere are investigated. To this end, source size, beam power and M(2) factor of source plane FT beam are derived. For a ...
  • Improved equivalent source theory 
    Umul, Yusuf Ziya (Optical Society of America, 2009-08)
    The equivalent source theorem, which is an important technique in the study of radiation and scattering by apertures, is improved by using the two axioms of the modified theory of physical optics. The method is applied to ...
  • Influence of turbulence on the effective radius of curvature of radial Gaussian array beams 
    Ji, Xiaohong; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Society of America, 2010-03-29)
    The analytical formula for the effective radius of curvature of radial Gaussian array beams propagating through atmospheric turbulence is derived, where coherent and incoherent beam combinations are considered. The influence ...
  • M-2-factor of coherent and partially coherent dark hollow beams propagating in turbulent atmosphere 
    Yuan, Yangsheng; Cai, Yangjian; Qu, Jun; Eyyuboğlu, Halil T.; Baykal, Yahya; Korotkova, Olga (Optical Society of America, 2009-09-28)
    Analytical formula is derived for the M-2-factor of coherent and partially coherent dark hollow beams (DHB) in turbulent atmosphere based on the extended Huygens-Fresnel integral and the second-order moments of the Wigner ...
  • Radiation force of coherent and partially coherent flat-topped beams on a Rayleigh particle 
    Zhao, Chengliang; Cai, Yangjian; Lu, Xuanhui; Eyyuboğlu, Halil T. (Optical Society of America, 2009-02-02)
    Propagations of coherent and partially coherent flat-topped beams through a focusing optical system are formulated. The radiation force on a Rayleigh dielectric sphere induced by focused coherent and partially coherent ...
  • Simulator for general-type beam propagation in turbulent atmosphere 
    Arpalı, Çağlar; Yazıcıoğlu, Canan; Eyyuboğlu, Halil T.; Altay Arpalı, Serap; Baykal, Yahya (Optical Society of America, 2006-10)
    A simulator is designed in MATLAB code which gives the propagation characteristics of a general-type beam in turbulent atmosphere. When the required source and medium parameters are entered, the simulator yields the average ...
