THz emission from Fe/Pt spintronic emitters with L1-FePt alloyed interface
Laura Scheuer, Moritz Ruhwedel, Dimitris Karfaridis +10
Recent developments in nanomagnetism and spintronics have enabled the use of ultrafast spin physics for terahertz (THz) emission. Spintronic THz emitters, consisting of ferromagnet…
Modification of spintronic terahertz emitter performance through defect engineering
Dennis M. Nenno, Laura Scheuer, Dominik Sokoluk +10
Spintronic ferromagnetic/non-magnetic heterostructures are novel sources for the generation of THz radiation based on spin-to-charge conversion in the layers. The key technological…
Towards loss compensated and lasing terahertz metamaterials based on optically pumped graphene
Peter Weis, Juan Luis Garcia-Pomar, Marco Rahm
It is evidenced by numerical calculations that optically pumped graphene is suitable for compensating inherent loss in terahertz (THz) metamaterials. In a first step, the complex c…
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…
Flat-face approximations of invisibility cloaks with planar metamaterial layers
Oliver Paul, Yaroslav Urzhumov, Christoffer Elsen +2
Transformation optics (TO) is a powerful tool for the design of artiffcial materials with unprecedented optical properties. Here, we propose the approximation of TO structures of a…
