Experimental analysis of true left-handed behaviour and transmission properties of composite metamaterials

Güven, Kaan; Aydın, Koray; Özbay, Ekmel (Elsevier, 2005-12)

We report the true left-handed transmission of a composite metamaterial (CMM) consisting of periodically stacked split-ring resonator (SRR) and wire elements. The negative permeability (μ < 0) gap is demonstrated explicitly ...
Negative refraction and subwavelength focusing using photonic crystals

Özbay, Ekmel; Aydın, Koray; Alıcı, Kamil Boratay; Güven, Kaan (SPIE, 2005-01)

We review certain novel optical properties of two-dimensional dielectric photonic crystals (PCs) which exhibit negative refraction behavior. We investigate two mechanisms which utilize the band structure of the PC and lead ...
Spectral negative refraction and focusing analysis of a two-dimensional left-handed photonic crystal lens

Güven, Kaan; Aydın, Koray; Alıcı, Kamil Boratay; Soukoulis, C. M.; Özbay, Ekmel (American Physical Society, 2004-11)

We report the spectral refraction analysis and focusing properties of a two-dimensional, dielectric photonic crystal (PC) slab in freespace. A transverse electric polarized upper band of the crystal is used. The measured ...
