Carrier-induced refractive index change in InN
(Wiley, 2008)Rapid development of InN technology demands comprehensive assessment of the electronic and optoelectronic potential of this material. In this theoretical work the effect of free electrons on the optical properties of the ... -
Chiral metamaterials with negative refractive index based on four "U" split ring resonators
(American Institute of Physics, 2010-08-23)A uniaxial chiral metamaterial is constructed by double-layered four "U" split ring resonators mutually twisted by 90°. It shows a giant optical activity and circular dichroism. The retrieval results reveal that a negative ... -
Effect of solvent refractive index on the surface plasmon resonance nanoparticle optical absorption
(2007)Optical properties of plasmon coupled silver and gold nanoparticles were studied as a function of the refractive index of the surrounding medium. Our studies confirmed that the effect of changes in the refractive index of ... -
Experimental study of subwavelength focusing by lefthanded metamaterials with a negative refractive index
(2007)Two dimensional (2D) left-handed metamaterials (LHM) exhibiting negative refraction and subwavelength imaging are studied experimentally. A left-handed transmission band is observed at the frequencies where both dielectric ... -
The magical world of metamaterials
(IEEE, 2009-10)In recent years, there has been a burgeoning interest in rapidly growing field of metamaterials due to their unprecedented properties unattainable from ordinary materials. Veselago pointed out that a material exhibiting ... -
Negative refraction and focusing by a left-handed material slab in free space
(IEEE, 2006)Negative refraction and focusing by a left-handed metamaterial (LHM) slab are experimentally verified. We measured refractive index of slab as -1.86. The flat lens behavior of LHM is demonstrated for two different point ... -
Negative refraction and subwavelength focusing using left-handed composite metamaterials
(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 ... -
Negative refraction and subwavelength focusing using photonic crystals
(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 ...
