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…
Metamaterial-based gradient index lens with strong focusing in the THz frequency range
Jens Neu, Bernd Krolla, Oliver Paul +3
The development of innovative terahertz (THz) imaging systems has recently moved in the focus of scientific efforts due to the ability to screen substances through textiles or plas…
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…
