Breaking Temporal Symmetries in Acoustic Metamaterials

Romain Christophe Rémy Fleury

We discuss our recent investigations on breaking time-reversal and spatio-temporal symmetries to provide novel functionalities in the field of metamaterials, with special emphasis on the field of acoustics and sound manipulation. ...

Filling the Entire Terahertz Frequency Gap by Single-Cycle MV/Cm Pulses

Christoph Peter Hauri, Fernando Ardana Lamas

We demonstrate highly efficient Terahertz production and absolute phase control in the hardly accessible THz frequency gap (1-15 THz) by optical rectification in organic crystals leading to single-cycle field oscillations beyond 150MV/m and 0.5 Tesla. ...

Absorption modulation of terahertz metamaterial by varying the conductivity of ground plane

Gabriel Aeppli, Joe Martin Bailey, Wanli Ma

Most research focuses on varying the resonator and dielectric spacer to configure the absorption and resonant frequency of terahertz (THz) metamaterial absorbers (MAs), where a metal ground plane is used as a perfect reflector of incident THz waves. In thi ...

Closed-cell crystalline foams: Self-assembling, resonant metamaterials

Alessandro Spadoni, Vladimir Dorodnitsyn

Internal degrees of freedom and periodic structure are critical requirements in the design of acoustic/elastic metamaterials since they can give rise to extraordinary properties like negative effective mass and stiffness. However, they are challenging to r ...

Tetradymites as Natural Hyperbolic Materials for the Near-Infrared to Visible

Klaus Kern, Pascal Gehring, Moritz Esslinger

Hyperbolic media exhibit unparalleld properties, e.g, as light absorbers in photovoltaics and photonics, as superlenses in far-field imaging, as subwavelength light concentrators in nanolithography, or as novel materials in emission engineering. With the a ...

Amer Chemical Soc2014

We report on compact and efficient laser-based THz generation in the terahertz frequency gap (1-10 THz). The radiation is generated by optical rectification of a midinfrared laser in a large-size, partitioned nonlinear organic crystal assembly. This enable ...

Liquid crystal plasmonic metamaterials

Toralf Scharf

Metamaterials today are often realized as complex structured metasurfaces. Their functionality is based on combination of plasmonic resonances in metallic nanostructures and interferences. Novel concepts of bottom up fabrication using liquid crystal self-o ...

Spin Waves in Artificial Crystals and Metamaterials Created from Nanopatterned Ni80Fe20 Antidot Lattices

Dirk Grundler

Periodic nanopatterning of metallic ferromagnets allows one to create devices with artificially tailored band structures for spin waves. We discuss our recent experiments performed on two-dimensional periodic lattices of nanoholes created in thin Ni80Fe20 ...
