Article Citation - WoS: 1Citation - Scopus: 1Scattering of Waves by a Half-Screen With Different Face Impedances: Closed Form Series Solution(Taylor & Francis Ltd, 2013) Umul, Yusuf Z.A novel series solution is obtained for the scattering problem of waves by a half-plane with different face impedances. The impedance condition is expressed in terms of the sum of Dirichlet and Neumann conditions, multiplied by appropriate coefficients. The scattering problem of plane waves by an interface between two half-planes with different impedances is also investigated. The results are compared with the literature, numerically.Article Citation - WoS: 9Citation - Scopus: 9Uniform Version of the Modified Theory of Physical Optics Based Boundary Diffraction Wave Theory(Taylor & Francis Ltd, 2008) Umul, Yusuf Z.The potential function of the modified theory of physical optics based boundary diffraction wave theory is made uniform by using the principles of the uniform theory of diffraction. The line integration of this new function along the edge contour gives the uniform diffracted fields which are finite for the transition regions of the diffraction geometry. The method is applied to the diffraction problem by the edge of a curved surface.Article Citation - WoS: 7Citation - Scopus: 8The Theory of the Boundary Diffraction Wave for Wedge Diffraction(Taylor & Francis Ltd, 2008) Umul, Yusuf Z.A new potential function, line integration which gives the edge diffracted fields, is constructed for wedge diffraction by using the method of modified theory of physical optics. The surface integrals are transformed into line integrals by the technique of asymptotic reduction. As an application of the novel potential function, the diffracted field is obtained for the geometry of a wedge for arbitrary incidence of plane waves.
