Spontaneous emission rates of dipoles in photonic crystal membranes
A. F. Koenderink, M. Kafesaki, C. M. Soukoulis +1
We show theoretically that finite two-dimensional (2D) photonic crystals in thin semiconductor membranes strongly modify the spontaneous emission rate of embedded dipole emitters.…
Numerical Investigation of Light Scattering off Split-Ring Resonators
S. Burger, L. Zschiedrich, R. Klose +6
Recently, split ring-resonators (SRR's) have been realized experimentally in the near infrared (NIR) and optical regime. In this contribution we numerically investigate light propa…
Cut-wire pairs and plate pairs as magnetic atoms for optical metamaterials
G. Dolling, C. Enkrich, M. Wegener +3
We study the optical properties of metamaterials made from cut-wire pairs or plate pairs. We obtain a more pronounced optical response for arrays of plate pairs -- a geometry which…
Spontaneous emission in the near-field of 2D photonic crystals
A. Femius Koenderink, M. Kafesaki, C. M. Soukoulis +1
We show theoretically that photonic crystal membranes cause large variations in the spontaneous emission rate of dipole emitters, not only inside but also in the near-field above t…
Limits on the amplification of evanescent waves of left-handed materials
Th. Koschny, R. Moussa, C. M. Soukoulis
We investigate the transfer function of the discretized perfect lens in finite-difference time-domain (FDTD) and transfer matrix (TMM) simulations; the latter allow to eliminate th…
Isotropic three-dimensional left-handed meta-materials
Th. Koschny, L. Zhang, C. M. Soukoulis
We investigate three-dimensional left-handed and related meta-materials based on a fully symmetric multi-gap single-ring SRR design and crossing continuous wires. We demonstrate is…
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…
