  • Scintillations of partially coherent multiple Gaussian beams in turbulence 
    Baykal, Yahya; Eyyuboğlu, Halil T.; Cai, Yangjian (Optical Soc Amer, 2009-04-01)
    For an incidence composed of partially coherent multiple Gaussian beams, Huygens-Fresnel principle-based on-axis scintillation index is formulated in a weakly turbulent homogeneous horizontal atmospheric path. Our general ...
  • Simplified uniform theory of diffraction 
    Umul, Yusuf Ziya (Optical Soc Amer, 2005-07-01)
    Simple exponential functions that approach zero for reflection and shadow boundaries are considered to cancel the infinite values of diffraction coefficients at these regions. This method is applied to a wedge diffraction ...
  • State of polarization of a stochastic electromagnetic beam in an optical resonator 
    Korotkova, Olga; Yao, Min; Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2008-11)
    On the basis of the unified theory of coherence and polarization, we investigate the behavior of the state of polarization of a stochastic electromagnetic beam in a Gaussian cavity. Formulations both in terms of Stokes ...
  • Structure functions in turbulence for incidence with arbitrary-field distribution 
    Baykal, Yahya (Optical Soc Amer, 2007-06)
    In a turbulent atmosphere, the log-amplitude, phase-correlation, and structure functions are formulated for light sources exhibiting arbitrary-field distribution. This is done by extending the formulations of the correlation ...
  • Twist phase-induced reduction in scintillation of a partially coherent beam in turbulent atmosphere 
    Wang, Fei; Cai, Yangjian; Eyyuboğlu, Halil T.; Baykal, Yahya (Optical Soc Amer, 2012-01-15)
    The scintillation index of a Gaussian Schell-model beam with twist phase (i.e., twisted GSM beam) in weak turbulent atmosphere is formulated with the help of a tensor method. Variations of the scintillation index of a ...
  • Uniform boundary diffraction wave theory of Rubinowicz 
    Umul, Yusuf Ziya (Optical Soc Amer, 2010-07)
    Rubinowicz introduced a uniform asymptotic evaluation of the boundary diffraction wave at the transition region [Ann. Phys. (Leipzig) 378, 339 (1924)]. The uniform theory of Rubinowicz is generalized for the improved ...
  • Uniform line integral representation of edge-diffracted fields 
    Umul, Yusuf Ziya (Optical Soc Amer, 2008-01)
    A uniform line integral representation is derived for edge-diffracted fields by using the modified theory of physical optics and uniform asymptotic evaluation methods. The method is applied to the problem of diffraction ...
  • Uniform theory for the diffraction of evanescent plane waves: publisher's note 
    Umul, Yusuf Ziya (Optical Soc Amer, 2007-09)
    A uniform diffracted field is obtained in terms of Fresnel functions with complex argument by subtracting the unit step function from the Fresnel integral. The method is applied to the problem of diffraction of inhomogeneous ...
  • Wave diffraction by a reflectionless half-plane 
    Umul, Yusuf Ziya (Optical Soc Amer, 2017-11-20)
    The concept of reflectionless surface is put forth, and its reflection and transmission coefficients are determined by using the scattered geometrical optics fields of transmissive and perfectly electric conducting surfaces. ...
  • Young-Kirchhoff-Rubinowicz theory of diffraction in the light of Sommerfeld's solution 
    Umul, Yusuf Ziya (Optical Soc Amer, 2008-11)
    Kirchhoff's theory of diffraction is derived by transforming the exact solution of Sommerfeld into surface integrals for the half-plane problem. It is shown that the exact solution directly yields the integral theorem of ...
