Article Citation - WoS: 1Citation - Scopus: 1Wave Diffraction by a Perfect Magnetic Conductor Half-Plane Between Free Space and Anisotropic Plasma(Elsevier Gmbh, 2020) Umul, Yusuf ZiyaThe diffraction of magnetic polarized electromagnetic plane waves by a perfect magnetic conductor half-screen, located between free space and anisotropic plasma, is studied. The method of transition boundary is used for the solution of the problem. The scattered GO wave is obtained. The diffracted fields are derived with the aid of the scattered GO wave. The uniform expressions of the edge diffracted waves are derived. The behaviors of the evaluated fields are investigated numerically.Article Citation - WoS: 1Citation - Scopus: 1Diffraction by an Anomalously Perfect Reflecting Metasurface Half-Plane(Elsevier Gmbh, 2020) Umul, Yusuf ZiyaThe scattering process of plane waves by a half-plane, composed of anomalously perfect reflecting surfaces, is investigated. The solution of the problem is obtained in an original way. The boundary condition of the problem is also taken into account in the construction of the edge diffracted field. The limiting case of the problem is the diffraction of waves by a perfect electric conductor half plane. The obtained field expression are analyzed numerically.Article Citation - WoS: 6Citation - Scopus: 6Directive Line Source Scattering by a Half-Plane Between Two Isorefractive Media(Elsevier Gmbh, Urban & Fischer verlag, 2017) Basdemir, Husnu DenizA perfectly conducting half-plane which is lying at the interface between two isorefractive media is investigated for a directive line source illumination. For this purpose, a directive line source is defined by passing a plane-wave from an aperture. Also, more suitable function than the Fresnel function is defined for cylindrical sources. The scattered field and its subfields are obtained by a new method. Consequently, all the mentioned fields are analyzed numerically. (C) 2016 Elsevier GmbH.

Because of the anomalous refraction property of left handed media, shadow boundary shifts toward to the lower surface of the half-plane. In order to obtain the shifted boundary, diffracted waves are divided to subfields. Thus, obtained diffracted waves compensates the deficiency of geometries optics fields at the transition regions. The uniform version of waves is obtained by using the uniform theory of diffraction. The wave behaviors are examined numerically.Article Citation - WoS: 12Citation - Scopus: 12Scattering of Waves by a Perfectly Conducting Wedge Residing at the Interface Between Two Isorefractive Media(Ieee-inst Electrical Electronics Engineers inc, 2016) Basdemir, Husnu DenizScattered field by a wedge that is surrounded by isorefractive media is analyzed. A series-based method is introduced and applied to the wedge problem with soft boundary condition. The fields are examined numerically. The numerical results show that the proposed method is suitable for analysis of these kinds of problems.
