  • Integral representation of the edge diffracted waves along the ray path of the transition region 
    Umul, Yusuf Ziya (Optical Soc Amer, 2008-09)
    The expression of the edge diffracted fields, in terms of the Fresnel integral, is transformed into a path integral. The obtained integral considers the integration of the incident field along the ray path of the transition ...
  • Modified diffraction theory of Kirchhoff 
    Umul, Yusuf Ziya (Optical Soc Amer, 2008-08)
    The diffraction theory of Kirchhoff is reinterpreted and a new form of a surface diffraction integral is developed by using the axioms of the modified theory of physical optics, which leads to the exact scattered fields ...
  • Modified theory of physical optics 
    Umul, Yusuf Ziya (Optical Soc Amer, 2004-10-04)
    A new procedure for calculating the scattered fields from a perfectly conducting body is introduced. The method is defined by considering three assumptions. The reflection angle is taken as a function of integral variables, ...
  • Modified theory of physical optics approach to wedge diffraction problems 
    Umul, Yusuf Ziya (Optical Soc Amer, 2005-01-10)
    The problem of diffraction from a perfectly conducting wedge is examined with the modified theory of physical optics (MTPO). The exact wedge diffraction coefficient is compared with the asymptotic edge waves of MTPO integral ...
  • 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 ...
  • 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 ...
