Aperiodic sources placed over periodic structures have attracted great interest from researchers of electromagnetics area. The analysis of such structures is a very challenging task since such an analysis must handle the infinite periodicity of the structure while also dealing with the aperiodic source over it which forbids a direct application of a periodic analysis to the problem. Full wave methods addressing these problems involve infinite summations and double integrations which make the analysis cumbersome. Homogenization based methods reduce the complexity of the analysis but at the expense of a loss of flexibility in handling different kinds of structures while the resulting Green's functions still need integrations as opposed to being in closed-form. The aim of this thesis is to propose a novel full-wave approach in obtaining closed-form expressions for the Green's functions of such structures which makes the analysis of these problems efficient while offering more flexibility compared to existing homogenization methods in the literature.

Numerical simulation of scour at the rear side of a coastal revetment Şentürk, Barış Ufuk; Guler, Hasan Gokhan; Baykal, Cüneyt (2023-05-01) This paper presents the results of a numerical modeling study on the scouring of unprotected rear side material of a rubble mound coastal revetment due to the overtopping of solitary-like waves utilizing a coupled hydro-morphodynamic computational fluid dynamics (CFD) model. Three cases having various wave heights are tested with six different turbulence models together with different wall functions. The hydrodynamic results (free-surface elevations, overtopping volumes, and jet thicknesses) and morphologic...
Closed-form Green's functions for cylindrically stratified media Tokgoz, C; Dural Ünver, Mevlüde Gülbin (2000-01-01) A numerically efficient technique is developed to obtain the spatial-domain closed-form Green's functions of the electric and magnetic fields due to z- and phi-oriented electric and magnetic sources embedded in an arbitrary layer of a cylindrical stratified medium. First, the electric- and magnetic-field components representing the coupled TM and TE modes are derived in the spectral domain for an arbitrary observation layer The spectral-domain Green's functions are then obtained and approximated in terms of...
Time-space fractional governing equations of transient groundwater flow in confined aquifers: Numerical investigation Tu, Tongbi; Ercan, Ali; Kavvas, M. Levent (2018-05-01) In order to model non-Fickian transport behaviour in groundwater aquifers, various forms of the time-space fractional advection-dispersion equation have been developed and used by several researchers in the last decade. The solute transport in groundwater aquifers in fractional time-space takes place by means of an underlying groundwater flow field. However, the governing equations for such groundwater flow in fractional time-space are yet to be developed in a comprehensive framework. In this study, a finit...
Generalized Hybrid Surface Integral Equations for Finite Periodic Perfectly Conducting Objects Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2017-01-01) Hybrid formulations that are based on simultaneous applications of diversely weighted electric-field integral equation (EFIE) and magnetic-field integral equation (MFIE) on periodic but finite structures involving perfectly conducting surfaces are presented. Formulations are particularly designed for closed conductors by considering the unit cells of periodic structures as sample problems for optimizing EFIE and MFIE weights in selected regions. Three-region hybrid formulations, which are designed by geneti...
CP asymmetry in b->sl(+)l(-) decay Alıyev, Tahmasıb; Iltan, E; Pak, NK (1996-07-01) Using the experimental upper bound on the neutron electric dipole moment and the experimental result on the b-->s gamma branching ratio we have calculated the CP asymmetry and Gamma(2HDM)(b-->sl(+)l(-))/Gamma(SM)(b-->sl(+)l(-)). It is shown that in the invariant dilepton mass q(2) region (m(psi)(2),+0.2 GeV2)<q(2)<m(b)(2) the CP asymmetry is maximal and quite detectable.
