Nano-particle mass sensing using phononic pillars

Bonhomme Jeremy, Oudich Mourad, Bahram Djafari-Rouhani, Sarry Frederic, Yan Pennec, Bonello Bernard, Beyssen Denis, Paul Charette

In this work, we investigate the sensitivity of a pillar based metasurface in order to understand the behavior of the system in real tests conditions where the mass perturbation will not be homogeneous on all the system. The structure we study is composed in stacking alternate layers of Silica and…

Enhanced adaptive cross-layer scheme for low latency HEVC streaming over Vehicular Ad-hoc Networks (VANETs)

Mohamed Aymen Labiod, M Gharbi, François-Xavier Coudoux, Patrick Corlay, Noureddine Doghmane

Vehicular communication has become a reality guided by various applications. Among those, high video quality delivery with low latency constraints required by real-time applications constitutes a very challenging task. By dint of its never-before-achieved compression level, the new High-Efficiency…

The electrostatically forced Faraday instability: theory and experiments

Kevin Ward, Satoshi Matsumoto, Ranga Narayanan

The onset of interfacial instability in two-fluid systems using a viscous, leaky dielectric model is studied. The instability arises as a result of resonance between the parametric frequency of an imposed electric field and the system's natural frequency. In addition to a rigorous model that…

Development of a Dual-band Printed Antenna Based on a Nanocomposite Material made of Polyaniline charged by Iron-Nickel Nanopowder

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, Lamine Kone, S. Bergheul, T. Lasri

One of the major challenges of printed electronics is to develop materials for flexible devices. Among these latter, antennas occupy a place of choice because of the new applications which are emerging. In this paper a flexible antenna based on a new nanocomposite, Polyaniline (PANI) charged by…

Electromagnetic physical modeling of a gallium nitride distributed transferred electron device based planar waveguide structure THz oscillator

Christophe Dalle

The potential of a planar waveguide structure terahertz oscillator based on a gallium nitride distributed transferred electron device is theoretically investigated. The circuit numerical physical modeling relies on a two-dimensional time-domain electromagnetism/transport simulator. It is based on…

An optical power divider based on mode coupling using GaN/Al2O3 for underwater communication

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, Tomy Abuzairi, El Hadj Dogheche

This paper details the design of a 1 \texttimes 8 optical power divider, using a gallium nitride (GaN) semiconductor on sapphire, which can be applied to underwater optical wireless communication. The design consists of nine parallel rectangular waveguides which are based on mode coupling phenomena…

FTIR and X-ray micro-tomography on Itokawa particles and carbonaceous chondrites

Rosario Brunetto, Zélia Dionnet, Alice Aléon-Toppani, Donia Baklouti, Ferenc Borondics, Zahia Djouadi, Andrew King, Tomoki Nakamura, Stefano Rubino, Christophe Sandt, David Troadec, Akira Tsuchiyama

We report a combined IR and X micro-tomography analysis of five particles from asteroid Itokawa and a few selected fragments of several carbonaceous chondrites. These techniques are an efficient first-step in a multi-technique analytical sequence to be applied on small Solar System bodies samples,…

Plasmon induced transparency in graphene-based side coupled two rectangular nano-cavities-like structures

A. Noual, M. Amrani, E.H. El Boudouti, Yan Pennec, Bahram Djafari-Rouhani

We investigate numerically the plasmon analogue of electromagnetic induced transparency (EIT) in a compact graphene-based waveguide coupled to two rectangular nano-cavities-like structures made out of graphene nanoribbons. The cavities are placed symmetrically on each side of the bus waveguide,…

A Comparative Investigation of Plasmonic Properties between Tunable Nanoobjects and Metallized Nanoprobes for Optical Spectroscopy

Damien Eschimese, Patrick Hsia, Francois Vaurette, D. Deresmes, De Philippe Bettignies, Joachim Schreiber, Marc Chaigneau, S. Arscott, Gaëtan Lévêque, Thierry Melin

In order to evaluate the optical efficiency of tip-based probes for future tip-enhanced optical spectroscopy applications, we developed an experimental setup based on the coupling of an achromatic inverted microscope equipped with a total internal reflection objective and an atomic force microscopy…
