Article Citation - WoS: 1Citation - Scopus: 1Three Dimensional Theory of the Boundary Diffraction Wave(Elsevier Gmbh, 2019) Umul, Yusuf ZiyaThe line integral of the boundary diffraction wave theory, which yields the diffracted fields by an edge discontinuity, is obtained from the surface integral of the modified theory of physical optics. The line integral is evaluated by using the edge point method. The generalization of the integral is performed for curved edges. In this case the kernel is a function of two variable angles.Article Citation - WoS: 5Citation - Scopus: 5Boundary Diffraction Wave Theory of Junctions Between Two Surfaces With Different Face Impedances(Elsevier Sci Ltd, 2012) Umul, Yusuf ZiyaThe line integral of the boundary diffraction wave theory is derived for the diffraction process of waves by a junction between two surfaces with different face impedances. The exact solution of Maliuzhinets is used with this aim. The resultant integral is applied to the diffraction of waves by a circular junction between two impedance surfaces. The results are examined numerically. (C) 2011 Elsevier Ltd.

The function is valid for arbitrary aspects of observation. The line integration of these functions gives the total scattered fields. The method is applied to the problem of diffraction of plane waves by an opaque half-plane for oblique incidence. (c) 2008 Elsevier Ltd. All rights reserved.
