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,…
Toy model for plasmonic metamaterial resonances coupled to two-level system gain
Martin Wegener, Juan Luis Garcia-Pomar, Costas M. Soukoulis +3
We propose, solve, and discuss a simple model for a metamaterial incorporating optical gain: A single bosonic resonance is coupled to a fermionic (inverted) two-level-system resona…
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…
Wide-angle perfect absorber/thermal emitter in the THz regime
Marcus Diem, Thomas Koschny, Costas M. Soukoulis
We show that a perfect absorber/thermal emitter exhibiting an absorption peak of 99.9% can be achieved in metallic nanostructures that can be easily fabricated. The very high absor…
