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…
Bulk Negative Index Photonic Metamaterials for Direct Laser Writing
Durdu Ö. Güney, Thomas Koschny, Maria Kafesaki +1
We show the designs of one- and two-dimensional photonic negative index metamaterials around telecom wavelengths. Designed bulk structures are inherently connected, which render th…
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…
Surface waves in photonic crystal slabs
Bingnan Wang, Weitao Dai, Anan Fang +4
Photonic crystals with a finite size can support surface modes when appropriately terminated. We calculate the dispersion curves of surface modes for different terminations using t…
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.
