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 ...

Rapid-Response Low Infrared Emission Broadband Ultrathin Plasmonic Light Absorber

Giulia Tagliabue, Dimos Poulikakos

Plasmonic nanostructures can significantly advance broadband visible-light absorption, with absorber thicknesses in the sub-wavelength regime, much thinner than conventional broadband coatings. Such absorbers have inherently very small heat capacity, hence ...

Physical bounds on absorption and scattering for cloaked sensors

Romain Christophe Rémy Fleury

We derive and discuss general physical bounds on the electromagnetic scattering and absorption of passive structures. Our theory, based on passivity and power conservation, quantifies the minimum and maximum allowed scattering for an object that absorbs a ...

Monolithic Metal-Coated Plastic Components for mm-Wave Applications

Jean-Philippe Ansermet, Arndt Christian von Bieren, Emile Jacques de Rijk, Alessandro Macor

A stereolithography-based manufacturing process for monolithic high aspect ratio components for mm-wave and sub-mm-wave applications is demonstrated. A 25mm long straight waveguide and a diagonal horn antenna, both for the WR-3.4 band (220–330 GHz), are ma ...

Optical forces and torques on realistic plasmonic nanostructures: a surface integral approach

Olivier Martin, Jérémy Butet

We develop a novel formalism to calculate the optical forces and torques on complex and realistic nanostructures by combining the surface integral equation (SIE) technique with Maxwell's stress tensor. The optical force is calculated directly on the scatte ...

System-level Assessment and Area Evaluation of Spin Wave Logic Circuits

Luca Gaetano Amarù, Odysseas Zografos

Spin Wave Devices (SWDs) are promising candidates for scaling electronics beyond the domain of CMOS. In contrast to traditional charge-based technologies, SWDs rely on propagating oscillation of magnetization as information carrier. Thanks to the intrinsic ...

Multi-Band Surface Enhanced Infrared Absorption Spectroscopy of Molecular Monolayers

Hatice Altug

We develop concepts for engineering multi-resonant infrared plasmonic antennas. We utilize these antennas in conjunction with a perfect absorber geometry to simultaneously enhance mid-infrared vibrational resonances separated by 3 mu m in in monolayer poly ...

Slowing, advancing and switching of microwave signals using circuit nanoelectromechanics

Tobias Kippenberg, Xiaoqing Zhou, Albert Schliesser

The parametric coupling of electromagnetic and mechanical degrees of freedom gives rise to a host of optomechanical phenomena. Examples include quantum-limited displacement measurements, sideband cooling or amplification of mechanical motion. Likewise, thi ...

Furtive quantum sensing using matter-wave cloaks

Romain Christophe Rémy Fleury

We introduce the concept of furtive quantum sensing, demonstrating the possibility of concealing quantum objects from matter waves while maintaining their ability to interact and to get excited by the impinging particles. This is obtained by cloaking, with ...

Electroacoustic metamaterials: achieving negative acoustic properties with shunt loudspeakers

Hervé Lissek

Acoustic metamaterials constitute a new class of structures that exhibit acoustic properties not readily available in nature. These properties can be a negative mass density, expressing the opposition of the acceleration of a particle to the application of ...
