The approximate theory proposed in reference [1] for viscoelastic layered composites is appraised by applying it to a transient wave propagation problem. The problem involves a viscoelastic slab subjected at one end to a dynamic pressure which has either step or trapezoidal variation in time while its other end is kept fixed. The faces of the slab are parallel to the layering. For the case in which the composite material is elastic, which can be obtained from viscoelastic case when viscous terms vanish, the wave profiles for normal stress and particle velocity are determined by using exact and approximate theories, and they are compared. It is found that even the lowest order approximate theory is capable of predicting the essential dynamic characteristics of the layered composite correctly. Further, the influence of the viscosity on wave profiles is studied by using the approximate theory. For the time integration of the approximate equations a numerical algorithm based on FFT is employed.

Voltammetric and drift spectroscopy investigation in dithiophosphinate-chalcopyrite system Guler, T; Hicyilmaz, C; Gokagac, G; Ekmekci, Z (Elsevier BV, 2004-11-01) The mechanism of dithiophosphinate (DTPI) adsorption on chalcopyrite was investigated by diffuse reflectance Fourier transformation (DRIFT) spectroscopy and by cyclic voltammetry (CV) at various pHs. CV experiments showed that the redox reactions occurred at a certain degree of irreversibility on the chalcopyrite surface in the absence of a collector due to preferential dissolution of iron ions in slightly acid solution and irreversible surface coverage by iron oxyhydroxides in neutral and alkaline solution...
First principles study on the structural, electronic, mechanical and lattice dynamical properties of XRhSb (X = Ti and Zr) paramagnet half-Heusler antimonides SÜRÜCÜ, GÖKHAN; CANDAN, ABDULLAH; Erkisi, Aytac; Gencer, Ayşenur; Güllü, Hasan Hüseyin (IOP Publishing, 2019-10-01) The half-Heusler TiRhSb and ZrRhSb alloys in the formation of face-centered cubic MgAgAs-type structure, which conforms to the F (4) over bar 3m space group with 216 as the space number, have been investigated using Generalized Gradient Approximation (GGA) implemented in Density Functional Theory (DFT). The calculated formation enthalpies and the plotted energy-volume curves of different types of structural phases (alpha, beta, and gamma) in these alloys indicate that the gamma-phase structure is the best e...
Form-Invariance of Maxwell's Equations in Waveguide Cross-Section Transformations Ozgun, Ozlem; Kuzuoğlu, Mustafa (Informa UK Limited, 2009-01-01) We present a novel coordinate transformation technique that controls the propagation of waves inside a waveguide, such that the waveguide behaves as if it is a reshaped waveguide. In this technique, the spatial domain of the waveguide is mapped to that of its reshaped equivalent, yielding an anisotropic medium inside the waveguide. In other words, the waveguide in the transformed space can be imagined as if it is filled with an anisotropic metamaterial whose spatially varying constitutive parameters reflect...
The effect of substrate and post-annealing temperature on the structural and optical properties of polycrystalline InSe thin films Parlak, Mehmet (Elsevier BV, 1998-06-08) X-ray diffraction, scanning electron microscopy, compositional analysis and transmission measurements are performed on InSe thin films grown by thermal evaporation at different substrate and annealing temperatures of 150-250 degrees C and 100-200 degrees C, respectively. An analysis of structural measurements indicates that there exist three phases of In-Se system like InSe, In2Se3 and In6Se7 in the same film at low-substrate temperature, but at high-substrate temperatures, In2Se3 phase was absent. The comp...
Excitonic effects on the nonlinear optical properties of small quantum dots KARABULUT, İBRAHİM; Safak, H.; Tomak, Mehmet (IOP Publishing, 2008-08-07) The excitonic effects on the nonlinear optical properties of small quantum dots with a semiparabolic confining potential are studied under the density matrix formalism. First, within the framework of the strong confinement approximation, we present the excitonic states and then calculate the excitonic effects on the nonlinear optical properties, such as second harmonic generation, third harmonic generation, nonlinear absorption coefficient and refractive index changes. We find the explicit analytical expres...
