Relating localized nanoparticle resonances to an associated antenna problem
Shakeeb Bin Hasan, Carsten Rockstuhl, Ralf Vogelgesang +1
We conceptually unify the description of resonances existing at metallic nanoparticles and optical nanowire antennas. To this end the nanoantenna is treated as a Fabry-Perot resona…
Homogenization of resonant chiral metamaterials
Andrei Andryieuski, Christoph Menzel, Carsten Rockstuhl +3
Homogenization of metamaterials is a crucial issue as it allows to describe their optical response in terms of effective wave parameters as e.g. propagation constants. In this pape…
An advanced Jones calculus for the classification of periodic metamaterials
Christoph Menzel, Carsten Rockstuhl, Falk Lederer
By relying on an advanced Jones calculus we analyze the polarization properties of light upon propagation through metamaterial slabs in a comprehensive manner. Based on symmetry co…
Strong influence of packing density in terahertz metamaterials
Ranjan Singh, Carsten Rockstuhl, Weili Zhang
We investigate the response of terahertz metamaterials made of split-ring resonators depending on the unit cell density. It is shown that the fundamental resonance has its highest…
Asymmetric transmission of linearly polarized light at optical metamaterials
C. Menzel, C. Helgert, C. Rockstuhl +4
We experimentally demonstrate a three-dimensional chiral optical metamaterial that exhibits an asymmetric transmission for forwardly and backwardly propagating linearly polarized l…
Plasmonic modes of extreme subwavelength nanocavities
Joerg Petschulat, Christian Helgert, Michael Steinert +6
We study the physics of a new type of subwavelength nanocavities. They are based on U-shaped metal-insulator-metal waveguides supporting the excitation of surface plasmon polariton…
Decomposing the scattered field of two-dimensional metaatoms into multipole contributions
J. Petschulat, J. Yang, C. Menzel +6
We introduce a technique to decompose the scattered near field of two-dimensional arbitrary metaatoms into its multipole contributions. To this end we expand the scattered field up…
High symmetry versus optical isotropy of a negative index metamaterial
Christoph Menzel, Andrei Andryieuski, Carsten Rockstuhl +4
Optically isotropic metamaterials (MMs) are required for the implementation of subwavelength imaging systems. At first glance one would expect that their design should be based on…
Cryogenic temperatures as a path towards high-Q terahertz metamaterials
Ranjan Singh, Zhen Tian, Jiaguang Han +3
Optical properties of planar thin film metamaterials were measured at room and liquid nitrogen temperatures using terahertz time-domain spectroscopy. The operation of metamaterials…
