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…
Optical microscopy via spectral modifications of a nano-antenna
T. Kalkbrenner, U. Hakanson, A. Schädle +3
The existing optical microscopes form an image by collecting photons emitted from an object. Here we report on the experimental realization of microscopy without the need for direc…
JCMmode: An Adaptive Finite Element Solver for the Computation of Leaky Modes
L. Zschiedrich, S. Burger, R. Klose +2
We present our simulation tool JCMmode for calculating propagating modes of an optical waveguide. As ansatz functions we use higher order, vectorial elements (Nedelec elements, edg…
FEM Modelling of 3D Photonic Crystals and Photonic Crystal Waveguides
S. Burger, R. Klose, A. Schaedle +2
We present a finite-element simulation tool for calculating light fields in 3D nano-optical devices. This allows to solve challenging problems on a standard personal computer. We p…
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…
