Cloaking and Invisibility: a Review

Invisibility has been a tantalizing concept for mankind over several centuries. With recent developments in metamaterial science and nanotechnology, the possibility of cloaking objects to incoming electromagnetic radiation has been escaping the realm of sc ...

Controlling Scattering and Absorption With Metamaterial Covers

Romain Christophe Rémy Fleury

We discuss the use of metasurfaces and plasmonic metamaterials to minimize the scattering from receiving antennas and sensors, with the goal of maximizing their absorption efficiency. We first analytically study and highlight the potential of these approac ...

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 ...

Single Crystal Silicon UHF Wine-Glass Ring Resonator with HfO2 Solid Dielectric Gap embedded in a Field Effect Transistor

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Emanuele Andrea Casu, Sara Rigante

In this work we present an ultra-high-frequency (UHF) single crystal silicon ring resonator with two embedded FETs. Electromechanical coupling is realized through a high-K, namely 10 nm HfO2, dielectric solid-gap sandwiched between the gate electrode and t ...

Study of spatial dispersion in graphene parallel-plate waveguides and equivalent circuit

Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

We propose an equivalent longitudinal circuit to characterize surface plasmon polaritons (SPPs) propagation along spatially dispersive graphene parallel plate waveguides. This circuit allows the fast analysis of the propagating modes, taking into account t ...

Acoustic supercoupling and enhancement of nonlinearities in density-near- zero (DNZ) metamaterial channels

Romain Christophe Rémy Fleury

Recent theoretical and experimental work has demonstrated that acoustic wave tunneling and energy squeezing can be achieved using density- near-zero (DNZ) metamaterial channels [Fleury et al, J. Acoust. Soc. Am., 132(3), 1956 (2012)]. These channels are di ...

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 ...

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 ...

Optimization of an acoustic leaky-wave antenna based on acoustic metamaterial

Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

In recent years, an increasing number of pioneering studies have been carried out in the field of acoustic metamaterials, following the path of electromagnetic metamaterials. These artificial engineered materials are designed in such a way so as to achieve ...

UV-Cured Epoxy-Zno Composites: Preparation and Characterization

Federica Sordo, Marco Sangermano

Epoxy-ZnO composites are prepared via UV-induced cationic polymerization. Complete unsoluble materials are achieved after 10min of irradiation. Thermal analyses shows an increase of T-g in the presence of the ZnO attributable to a strong hindrance effect o ...
