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…
Twisted split-ring-resonator photonic metamaterial with huge optical activity
M. Decker, R. Zhao, C. M. Soukoulis +2
Coupled split-ring-resonator metamaterials have previously been shown to exhibit large coupling effects, which are a prerequisite for obtaining large effective optical activity. By…
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…
Self-consistent calculation of metamaterials with gain
A. Fang, Th. Koschny, M. Wegener +1
We present a computational scheme allowing for a self-consistent treatment of a dispersive metallic photonic metamaterial coupled to a gain material incorporated into the nanostruc…
Inverse-designed 3D laser nanoprinted phase masks to extend the depth of field of imaging systems
T. J. Sturges, M. Nyman, S. Kalt +5
In optical imaging, achieving high resolution often comes at the expense of a shallow depth of field. This means that when using a standard microscope, any minor movement of the ob…
Student experiences of virtual reality - a case study in learning special relativity
D. McGrath, M. Wegener, T. J. McIntyre +2
We present a study of student learning through the use of virtual reality. A software package is used to introduce concepts of special relativity to students in a game-like environ…
Lineshape of harmonic generation on metal nanoparticles and metallic Photonic Crystal slabs
M. W. Klein, T. Tritschler, M. Wegener +1
We study the linear- and nonlinear-optical lineshapes of metal nanoparticles (theory) and metallic photonic crystal slabs (experiment and theory). For metal nanoparticle ensembles,…
Active control of a plasmonic metamaterial for quantum state engineering
S. A. Uriri, T. Tashima, X. Zhang +7
We experimentally demonstrate the active control of a plasmonic metamaterial operating in the quantum regime. A two-dimensional metamaterial consisting of unit cells made from gold…
Teaching Physics Using Virtual Reality
C. M. Savage, D. McGrath, T. J. McIntyre +2
We present an investigation of game-like simulations for physics teaching. We report on the effectiveness of the interactive simulation "Real Time Relativity" for learning special…
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…
