Ferroelectrics based absorbing layers

Jianping Hao, Véronique Sadaune, Ludovic Burgnies, Didier Lippens

We show that ferroelectrics-based periodic structure made of BaSrTiO3 (BST) cubes, arrayed onto a metal plate with a thin dielectric spacer film exhibit a dramatic enhancement of absorbance with value close to unity. The enhancement is found around the Mie magnetic resonance of the Ferroelectrics...

UV and IR laser induced ablation of Al2O3/SiN:H and a-Si:H/SiN:H

T. Schutz-Kuchly, A. Slaoui, J. Zelgowski, A. Bahouka, M. Pawlik, Jean-Pierre Vilcot, E. Delbos, M. Bouttemy, R. Cabal

Experimental work on laser induced ablation of thin Al2O3(20 nm)/SiN:H (70 nm) and a-Si:H (20 nm)/SiN:H (70 nm) stacks acting, respectively, as p-type and n-type silicon surface passivation layers is reported. Results obtained using two different laser sources are compared. The stacks are...

Polarization properties of specular and dense multipath components in a large industrial hall

Isabelle Vin, Davy Gaillot, Emmeric Tanghe, Wout Joseph, Pierre Laly, M. Lienard, Luc Martens

This paper presents a comprehensive analysis of the polarization characteristics of specular and dense multipath components in a large industrial hall, based on frequency-domain channel sounding experiments at 1.3 GHz. The RiMAX maximum-likelihood estimator is used to extract the full-polarimetric...

Robust receiver in impulsive noise

Xin Yan, Laurent Clavier, Ido Nevat, Gareth W. Peters, François Septier

Impulsive interference is a strong limitation in ultra wide band systems or ad hoc networks. Using stochastic geometry without considering a guard zone around the receiver leads to an alpha-stable distribution for this interference. Based on this assumption, it is possible to design efficient...

Approach-to-equilibrium molecular dynamics for thermal conductivies and boundary conductances

Pier Luca Palla, Evelyne Lampin, Pierre-Arnaud Francioso, Fabrizio Cleri

Thermal transport is simulated at the atomic scale by approach-to-equilibrium molecular dynamics simulations (AEMD) [1]. In this method, a hot and a cold regions are delimited, before the approach-to-equilibrium is simulated by releasing the thermal constraint. The temperature difference between...

Silicon pillars as resonators in an acoustical metamaterial

B. Bonello, R. Marchal, R. Moiseyenko, Yan Pennec, Bahram Djafari-Rouhani, J. Zhao, O. Boyko

We have investigated the propagation of Lamb waves in structures made of either an isolated resonant pillar or a set of pillars arranged in a line on a thin plate. The resonators as well as the plate are made of silicon. FEM computations show that two bending modes and one compressional mode are...

Deformation of droplets with magnetic nanoparticles in a rotating magnetic field

Sergey S. Koshelyuk, Yu V. Pylnov, Vladimir L. Preobrazhensky, Philippe Pernod

This paper investigates the change in contact angle of droplets of fluid containing dispersed nanoparticles (nanofluid) stabilized in oleic acid and ethanol placed in a rotating magnetic field. Paramagnetic nanoparticles with an average size 100 nm were injected into the droplets and situated on...

Multi-phonon scattering processes in one-dimensional anharmonic biological superlattices : understanding the dissipation of mechanical waves in mineralized tissues

Pierre-Yves Guerder, Alix C. Deymier-Black, Nichlas Z. Swinteck, Jerome O. Vasseur, Olivier Bou Matar, Krishna Muralidharan, Pierre A. Deymier

The scattering of elastic waves in a one dimensional phononic (PnC) crystal composed of alternate collagen and hydroxy-apatite constituent layers is studied. These superlattices are metaphors for mineralized tissues present in bones and teeth. The collagen is treated as an open system elastic...
