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…
Strong diamagnetic response of metamaterials
E. N. Economou, Th. Koschny, C. M. Soukoulis
We demonstrate that there is a strong diamagnetic response of metamaterials, consisting of open or closed split ring resonators (SRRs). Detailed numerical work shows that for dense…
An efficient way to reduce losses of left-handed metamaterials
Jiangfeng Zhou, Thomas Koschny, Costas M. Soukoulis
We propose a simple and effective way to reduce the losses in left-handed metamaterials by manipulating the values of the effective parameters R, L, and C. We investigate the role…
Size Dependence and Convergence of the Retrieval Parameters of Metamaterials
Jiangfeng Zhou, Thomas Koschny, Maria Kafesaki +1
We study the dependence of the retrieval parameters, such as the electric permittivity, the magnetic permeability and the index of refraction, , on the size of the unit cell of…
Magnetic and Electric Excitations in Split Ring Resonators
Jiangfeng Zhou, Thomas Koschny, Costas M. Soukoulis
We studied the electric and magnetic resonance of U-shaped SRRs. We showed that higher order excitation modes exist in both of the electric and magnetic resonances. The nodes in th…
Magnetic metamaterials at telecommunication and visible frequencies
C. Enkrich, M. Wegener, S. Linden +6
Arrays of gold split-rings with 50-nm minimum feature size and with an LC resonance at 200-THz frequency (1500-nm wavelength) are fabricated. For normal incidence conditions, they…
