Article Citation - WoS: 4Citation - Scopus: 5Interaction of Plane Waves by a Half-Screen Between Two Different Media(Springer, 2018) Umul, Yusuf ZiyaThe diffraction process of plane waves by a perfectly electric conducting half-screen, residing at a planar junction between two different media, is investigated. The scattered geometrical optics waves are evaluated by subtracting the initial fields from the total geometrical optics waves. The diffracted waves are obtained from the scattered geometrical optics fields by using a relation at the transition boundaries. The diffracted waves are expressed separately for both of the media. The uniform representations of the diffracted fields are obtained by using the uniform theory of diffraction. The scattered fields are analyzed numerically.Article Citation - WoS: 3Citation - Scopus: 3A Hybrid Maliuzhinets/Po Method for Diffraction Problems by Impedance Wedges(Elsevier Science Bv, 2011) Umul, Yusuf ZiyaThe solution of Maliuzhinets of the diffraction problem of waves by an impedance wedge is transformed into a physical optics integral. The resultant expression is suitable for the investigation of various diffraction problems having impedance wedges. The method is applied to the scattering of waves by an impedance spherical reflector with wedge structure at its discontinuity. The results are examined numerically. (C) 2011 Elsevier B.V.
