Negative effective mass density of acoustic metamaterial plate decorated with low frequency resonant pillars

Mourad Oudich, Bahram Djafari-Rouhani, Yan Pennec, M. Badreddine Assouar, Bernard Bonello

We investigate the elastic wave dispersion by a phononic metamaterial plate containing low frequency resonator stubs arranged periodically over the plate. We show that this system not only provides stop bands for wavelengths much larger than the periodicity but also displays negative behavior of…

Optimization of the optical properties of nanostructured silicon surfaces for solar cell applications

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini-Robbe, Tao Xu, Yannick Lambert, Yves Deblock, Marc Faucher, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping in solar cell. We present simulations on both the optical properties and the efficiency of micro pillars--MPs--or nanocones--NCs--silicon based solar cells together with measurements on their associated…

Electrical and Chemical studies on Al2O3 passivation activation process

M. Pawlik, J-P. Vilcot, M. Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Al2O3 deposited using Atomic layer Deposition (ALD) technique is known as an excellent material for p-type silicon surface passivation. However a post-deposition annealing step is needed to make the passivation effective. Thanks to coupled electrical measurements (capacitance and photoconductance)…

Joint estimation of state and noise parameters in a linear dynamic system with impulsive measurement noise: Application to OFDM systems

Nouha Jaoua, Emmanuel Duflos, Philippe Vanheeghe, Laurent Clavier, François Septier

Interference mitigation is one of the main challenges in wireless communication, especially in ad hoc networks. In such context, the Multiple Access Interference (MAI) is known to be of an impulsive nature. Therefore, the conventional Gaussian assumption is inadequate to model this type of…

Caractérisation non linéaire de films minces de (Pb,Sr)TiO3

Freddy Ponchel, Ludovic Burgnies, Damien Ducatteau, Eric Lheurette, Denis Remiens, Didier Lippens

Ce travail traite de la caractérisation diélectrique haute fréquence, en petit et en grand signal, de films minces ferroélectriques déposées sur silicium haute résistivité. Quel que soit le régime de fonctionnement la structure utilisée est un guide d'onde coplanaire sans discontinuité avec…

Determination of noise figure of differential circuits using correlation of output noise waves

Yogadissen Andee, J. Prouvée, F. Graux, Francois Danneville

The noise characterisation of differential circuits is considered. A new method for the determination of the differential mode noise power at the output of these circuits is presented. It is demonstrated that this differential noise power depends not only on the output noise powers but also on the…

CW Radar for Monitoring Water-to-Cellular Concrete

Kamel Haddadi, Tuami Lasri

The physical deterioration of concrete structures is mainly caused by their moisture content. Consequently, methods dedicated to contactless, non-destructive and real-time monitoring of moisture content levels are required to control the deterioration of buildings. In this study, we propose an…
