Article Citation - WoS: 5Citation - Scopus: 6Scattering of Waves by a Half-Screen Between Isorefractive Media(Elsevier Gmbh, 2018) Umul, Yusuf ZiyaThe scattering process of plane electromagnetic waves by a perfectly conducting half-plane, residing between isorefractive media, is investigated. The semi-infinite interface between two different media is modeled by using a resistive surface, since it causes the reflection and transmission of the incident wave. Thus the scenario is reduced to the diffraction problem of waves by the junction of two half-screens. The diffracted field is expressed with the aid of the split function that occurs in the Wiener-Hopf factorization of the scattered waves by imperfectly conducting half-planes. The total, geometrical optics and diffracted waves are analyzed numerically. (C) 2017 Elsevier GmbH.

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. All rights reserved.
