Negative refractive index due to chirality
Jiangfeng Zhou, Jianfeng Dong, Thomas Koschny +2
We demonstrate experimentally and numerically that metamaterials based on bilayer cross wires give giant optical activity, circular dichroism, and negative refractive index. The pr…
Negative refractive index response of weakly and strongly coupled optical metamaterials
Jiangfeng Zhou, Thomas Koschny, Maria Kafesaki +1
e present a detailed study of the retrieved optical parameters, electrical permittivity, magnetic permeability and refractive index, of the coupled fishnet metamaterial structures…
Nonplanar Chiral Metamaterials with Negative Index
Bingnan Wang, Jiangfeng Zhou, Thomas Koschny +1
We demonstrate experimentally and numerically that nonplanar chiral metamaterials give giant optical activity, circular dichroism, and negative refractive index. The transmission,…
Transmission in the vicinity of the Dirac point in hexagonal Photonic Crystals
Marcus Diem, Thomas Koschny, C. M. Soukoulis
We use a scattering matrix approach to simulate the transmission through a hexagonal Photonic Crystal in the vicinity of the Dirac point. If the crystal is oriented so that the pro…
3D-Chiral Metamaterial Showing Artificial Magnetic Response and Negative Refraction
E. Plum, J. Dong, J. Zhou +4
Artificial magnetism, negative permeability and negative refractive index are demonstrated in 3D-chiral metamaterial that shows giant polarization rotation and circular dichroism.
Experimental demonstration of negative index of refraction
Jiangfeng Zhou, Thomas Koschny, Lei Zhang +2
We introduce an improved and simplified structure made of periodic arrays of pairs of H-shaped metallic wires that offer a potentially simpler approach in building negative-index m…
