Article Citation - WoS: 2Citation - Scopus: 5Scattering of Plane Waves at the Junction of Two Corrugated Half-Planes(Taylor & Francis inc, 2005) Serbest, AH; Kara, A; Lueneburg, EIn this paper, the boundary conditions given by Weinstein ( 1969) are employed to simulate two corrugated half-planes with the same slot height but different slot width. The scattering mechanism at the junction of these half-planes is investigated via the Fourier transform technique, which leads to two coupled Wiener - Hopf equations. The solution of the Wiener - Hopf system is obtained by the Daniele - Khrapkov method and some numerical results are presented about the analysis of the scattered field.Article Citation - WoS: 1Citation - Scopus: 2Envious Gazes and Evil Eye Beads: a Self-Psychological Perspective on the Evil Eye(Taylor & Francis inc, 2024) Turkarslan, Kutlu Kagan; Kozak, Ekin DogaThe evil eye, the harmful effects of the envious gaze, is a common superstitious belief in many societies around the world, including Turkey. Since ancient times, people have developed a wide variety of practices and rituals to ward off the evil eye. It is generally believed that the evil eye is motivated by one of the most challenging emotions, envy. The discussion of envy has a long history in psychoanalysis. Unfortunately, psychoanalytic self-psychology has neglected envy and confined it to the concept of fragmentation products. This paper aims to contribute a self-psychological understanding of an envy-related cultural concept, the evil eye. The evil eye-related phenomena in Turkey, such as the harmful potential of gazes, the use of talismans and amulets for protection, and the fear of praising and exhibition, are discussed from a self-psychological perspective. Several short clinical vignettes delineating the evil eye in clinical practice are presented.Article Citation - WoS: 23Citation - Scopus: 27Comparison of Improved Slope Uniform Theory of Diffraction With Some Geometrical Optic and Physical Optic Methods for Multiple Building Diffractions(Taylor & Francis inc, 2009) Tabakcioglu, M. B.; Kara, A.This article presents a review of diffraction algorithms based on the uniform theory of diffraction for multiple building transition zone diffractions and proposes an improved uniform theory of diffraction model for fast and more accurate field prediction for multiple diffractions. The proposed method is based on the improved version of the slope uniform theory of diffraction and Fresnel zone concept, called the slope uniform theory of diffraction with convex hull. This article also provides a comparison for uniform theory of diffraction based algorithms and discusses the results for computation time and accuracy. Furthermore, the slope uniform theory of diffraction and the slope uniform theory of diffraction with convex hull methods are compared with a physical optics solution based on numerical computation of the Kirchhoff-Huygens integrals. Results of extensive simulations are presented and discussed for the development of fast and accurate radio network planning tools.Article Citation - WoS: 19Citation - Scopus: 22Improvements on Slope Diffraction for Multiple Wedges(Taylor & Francis inc, 2010) Tabakcioglu, Mehmet Baris; Kara, AliThis article proposes an improved slope uniform theory of diffraction model for fast and more accurate field prediction for multiple wedge diffractions in the transition zone. The proposed method is based on the slope uniform theory of diffraction and the Fresnel zone concept, called the slope uniform theory of diffraction with convex hull. The article also provides simulation results for the comparison of the uniform theory of diffraction based algorithms with respect to the computation time and accuracy.
