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,…
