Analysis of edge waves due to a point source in the presence of a PEC wedge

Ghassemiparvin, Behnam; Altıntaş, Ayhan (IEEE, 2014)

In this paper, we investigate the behavior of the field in the paraxial region of a perfectly conducting wedge and analyze the guiding effect of the wedge. It is observed that as the wedge angle increases, the guidance ...
Negative refraction and subwavelength focusing using left-handed composite metamaterials

Özbay, Ekmel; Aydın, Koray (SPIE, 2008-01)

We review experimental studies performed on left-handed metamaterials (LHM) at microwave frequencies. The metamaterial structure is composed of periodic arrays of split-ring resonators and wire meshes and exhibits a ...
Thereconstruction quality improvement of holographic stereograms via variable size segmentation

Şahin, Erdem; Onural, Levent; Kang, Hoonjong (IEEE, 2010)

As computer generated holograms becomes more common, the fast computation of holographic interference patterns in digital environment becomes a necessity. Since the computation time of holograms via Fresnel (or ...
