Image formation properties and inverse imaging problem in aperture based scanning near field optical microscopy
S. Schmidt, A. E. Klein, T. Paul +7
Aperture based scanning near field optical microscopes are important instruments to study light at the nanoscale and to understand the optical functionality of photonic nanostructu…
Tunable Graphene Antennas for Selective Enhancement of THz-Emission
R. Filter, M. Farhat, M. Steglich +3
In this paper, we will introduce THz graphene antennas that strongly enhance the emission rate of quantum systems at specific frequencies. The tunability of these antennas can be u…
Contribution of the magnetic resonance to the third harmonic generation from a fishnet metamaterial
J. Reinhold, M. R. Shcherbakov, A. Chipouline +9
We investigate experimentally and theoretically the third harmonic generated by a double-layer fishnet metamaterial. To unambiguously disclose most notably the influence of the mag…
Doubly resonant optical nanoantenna arrays for polarization resolved measurements of surface-enhanced Raman scattering
J. Petschulat, D. Cialla, N. Janunts +9
We report that rhomb-shaped metal nanoantenna arrays support multiple plasmonic resonances, making them favorable bio-sensing substrates. Besides the two localized plasmonic dipole…
A simple and versatile analytical approach for planar metamaterials
J. Petschulat, A. Chipouline, A. Tuennermann +5
We present an analytical model which permits the calculation of effective material parameters for planar metamaterials consisting of arbitrary unit cells (metaatoms) formed by a se…
Terahertz metamaterial with asymmetric transmission
R. Singh, E. Plum, C. Menzel +6
We show for the first time that a planar metamaterial, an array of coupled metal split-ring resonators with a unit cell lacking mirror symmetry, exhibits asymmetric transmission of…
