In-Plane Focusing of Terahertz Surface Waves on a Gradient Index Metamaterial Film
Martin F. Volk, Benjamin Reinhard, Jens Neu +2
We designed and implemented a gradient index metasurface for the in-plane focusing of confined terahertz surface waves. We measured the spatial propagation of the surface waves by…
Metamaterial near-field sensor for deep-subwavelength thickness measurements and sensitive refractometry in the terahertz frequency range
Benjamin Reinhard, Klemens M. Schmitt, Viktoria Wollrab +3
We present a metamaterial-based terahertz (THz) sensor for thickness measurements of subwavelength-thin materials and refractometry of liquids and liquid mixtures. The sensor opera…
Hybridization Induced Transparency in composites of metamaterials and atomic media
Peter Weis, Juan Luis Garcia-Pomar, René Beigang +1
We report hybridization induced transparency (HIT) in a composite medium consisting of a metamaterial and a dielectric. We develop an analytic model that explains HIT by coherent c…
Nonlinearity and optical bistability caused by local field effects in the interaction between a two level atomic system and a metamaterial
J. L. Garcia-Pomar, R. Beigang, M. Rahm
We present a theoretical analysis of the nonlinear response of a metamaterial consisting of an array of split ring resonators coupled to a two level atomic system (2LS) without inv…
Gradient Index Metamaterial Based on Slot Elements
Oliver Paul, Benjamin Reinhard, Bernd Krolla +2
We present a gradient-index (GRIN) metamaterial based on an array of annular slots. The structure allows a large variation of the effective refractive index under normal-to-plane i…
Experimental and numerical studies of terahertz surface waves on a thin metamaterial film
Benjamin Reinhard, Oliver Paul, Rene Beigang +1
We present experimental and numerical studies of localized terahertz surface waves on a subwavelength-thick metamaterial film consisting of in-plane split-ring resonators. A simple…
Highly Selective Terahertz Bandpass Filters Based on Trapped Mode Excitation
Oliver Paul, Rene Beigang, Marco Rahm
We present two types of metamaterial-based spectral bandpass filters for the terahertz (THz) frequency range. The metamaterials are specifically designed to operate for waves at no…
Strongly birefringent cut-wire pair structure as negative index wave plates at THz frequencies
P. Weis, O. Paul, C. Imhof +2
We report a new approach for the design and fabrication of thin wave plates with high transmission in the terahertz (THz) regime. The wave plates are based on strongly birefringent…
