Homogenization of Microwave Metamaterial Structures Using Full-Wave Solutions and Genetic Algorithms İbili, Hande; Ergül, Özgür Salih (2018-11-02) Metamaterials involve small details that create challenges in their numerical analysis. As commonly practiced, homogenization of such complex structures may simplify and facilitate their numerical solutions. However, homogenization should be performed carefully to avoid excessive modeling errors, especially for finite structures. In this paper, we present accurate homogenization of three-dimensional metamaterials involving split-ring resonators (SRRs). Electromagnetic characteristics of finite SRR structure...
Homogenization of ECAPed Al 2024 alloy through age-hardening KOTAN, G.; TAN, E.; Kalay, Yunus Eren; Gür, Cemil Hakan (2013-01-01) Mechanical properties of aluminum alloys can be improved by obtaining ultra-fine grained structures via severe plastic deformation methods such as equal channel angular pressing (ECAP). In practice, however, the final structure may not be as homogeneous as desired. Thus, elimination of the inhomogeneity of ECAPed samples is a challenging task. In the case of age-hardenable alloys, a combination of ECAP and aging might provide new means of obtaining microstructural homogeneity. In this study, the effect of p...

Perturbation analysis of sheath evolution, with application to plasma source ion implantation Bektursunova, RM; Demokan, O (IOP Publishing, 2001-02-07) A perturbation model has been developed to describe the evolution of an expanding plasma sheath around a cathode after a high-voltage negative pulse is applied to the cathode, simulating the conditions in devices such as those used for plasma source ion implantation. The set of governing equations consists of two coupled collisionless fluid equations for ions, and Poisson's equation and Boltzmann's assumption for electrons. The time-dependent, self-consistent expressions for the potential, ion density and i...
