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 ...

Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons

Olivier Martin, Thomas Gerd Siegfried, Arash Farhang

Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...

Focusing and Extraction of Light mediated by Bloch Surface Waves

Hans Peter Herzig, Elsie Barakat

The control of emission from localized light sources is an objective of outstanding relevance in nanophotonics. In a recent past, a large number of metallic nanostructures has been proposed to this end, wherein plasmonic modes are exploited as energy carri ...

Handheld high-throughput plasmonic biosensor using computational on-chip imaging

Hatice Altug, Arif Engin Cetin, Min Huang

We demonstrate a handheld on-chip biosensing technology that employs plasmonic microarrays coupled with a lens-free computational imaging system towards multiplexed and high-throughput screening of biomolecular interactions for point-of-care applications a ...

Punching strength of actual two-way slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

Many building codes rely on empirical formulations with respect to the punching shear design provisions. Such empirical equations are typically calibrated on the basis of laboratory tests performed on simplified geometries (usually isolated specimens) with ...

Predicting Input Impedance and Efficiency of Graphene Reconfigurable Dipoles Using a Simple Circuit Model

Julien Perruisseau-Carrier, Michele Tamagnone

An analytical circuit model able to predict the input impedance of reconfigurable graphene plasmonic dipoles is presented. A suitable definition of plasmonic characteristic impedance, employing natural currents, is used to for consistent modeling of the an ...

Manipulation of electron flow using near-zero index semiconductor metamaterials

Romain Christophe Rémy Fleury

We study the possibility of controlling the propagation of ballistic electrons using an electronic metamaterial with zero quantum index of refraction. This is obtained by tailoring the band structure of a semiconductor superlattice to exhibit a Dirac cone ...

Parallel Transduction of Nanomechanical Motion Using Plasmonic Resonators

Tobias Kippenberg

We demonstrate parallel transduction of thermally driven mechanical motion of an array of gold-coated silicon nitride nanomechanical beams, by using near-field confinement in plasmonic metal-insulator metal resonators supported in the gap between the gold ...

Parity-time symmetric metamaterials and metasurfaces for loss-immune and broadband acoustic wave manipulation

Romain Christophe Rémy Fleury

We explore the largely uncharted scattering properties of acoustic systems that are engineered to be invariant under a special kind of space-time symmetry, consisting in taking their mirror image and running time backwards. Known as Parity-Time symmetry, t ...

Negative Refraction and Planar Focusing Based on Parity-Time Symmetric Metasurfaces

Romain Christophe Rémy Fleury

We introduce a new mechanism to realize negative refraction and planar focusing using a pair of parity-time symmetric metasurfaces. In contrast to existing solutions that achieve these effects with negative-index metamaterials or phase conjugating surfaces ...
