A millimeter-wave elastomeric microstrip phase shifter

S. Hage-Ali, Yovan Orlic, Nicolas Tiercelin, Ronan Sauleau, Vladimir Preobrazhensky, Philippe Pernod, Philippe Coquet

This communication reports an innovative lowcost millimeter-wave microstrip phase shifter using the mechanical reconfiguration of a metallized polydimethylsiloxane (PDMS) elastomeric ground plane. The reconfigurable ground plane is used to tune an air gap under a fused quartz substrate, inducing a…

Vitro study of the impact of sédimentsartificiellement contaminated with anthracene: Effects on indigenous bacteria and the marine nematode [Étude in vitro de l'impact de sediments artificiellement contaminés par l'anthracène: Effets sur les bactéries indigènes et les nématodes libres marins]

O.B. Said, Hela Louati, A. Soltani, E. Mahmoudi, Cristiana Cravo-Laureau, O. Pringault, Robert Duran, P. Aissa

This study evaluates the in vitro impact of three bioremediation techniques: biostimulation, bioaugmentation, and a combination of biostimulation and bioaugmentation on microflora and nematofauna after an artificial contamination of lagoon sediments by anthracene. This sediment contamination tends…

Growth mechanism investigation of SnO2 thin films deposited by aerosol pyrolysis for biosensor applications: Importance of the thickness

V. Stambouli, M. Manesse, F. Ferrieu, L. Rapenne, Hervé Roussel, P. Chaudouet, Sabine Szunerits

Transparent conductive oxide films are suitable sensitive layers for gas sensors and biosensors, provided that their intrinsic properties are controlled, notably considering their thickness dependence. The present paper reports on a study of the variation of some physical properties of…

Searching for THz Gunn oscillations in GaN planar nanodiodes

Ana Iniguez-De-La-Torre, Ignacio Íñiguez-De-La-Torre, Javier Mateos, Tomás González, Paul Sangare, Marc Faucher, Bertrand Grimbert, Virginie Brandli, Guillaume Ducournau, Christophe Gaquière

A detailed study of GaN-based planar asymmetric nanodiodes, promising devices for the fabrication of room temperature THz Gunn oscillators, is reported. By using Monte Carlo simulations, an analysis of the static I-V curves and the time-domain evolution of the current obtained when varying some…

Non-radiative complete surface acoustic wave bandgap for finite-depth holey phononic crystal in lithium niobate

Didit Yudistira, Yan Pennec, Bahram Djafari-Rouhani, Samuel Dupont, Vincent Laude

We demonstrate the existence of non-radiative complete surface acoustic wave(SAW)bandgaps for two-dimensional piezoelectric phononic crystals of holes. Holes of finite depth in a semi-infinite LiNbO3 substrate are specifically considered. SAWbandgaps are determined from the band structure…

Hall-effect measurements of sol-gel derived CuInS2 thin films for photovoltaic applications

Bourlier Yoan, Rémy Bernard, C. Lethien, Pascal Roussel, Malek Zegaoui, Mohamed Bouazaoui, N. Rolland, Paul-Alain Rolland

CuInS2 thin films were prepared via the sol-gel process. X-ray diffraction (XRD) studies reveal that the thin films are well crystallized and they crystallize in a chalcopyrite phase. Hall-effect measurements were carried out, for the first time, on chalcopyrite CuInS2 films elaborated by the sol-…

PEDOT Based Conducting IPN Actuators: Effects of Electrolyte on Actuation

Cedric Plesse, Alexandre Khaldi, Caroline Soyer, Eric Cattan, Dominique Teyssié, Claude Chevrot, Frédéric Vidal

Actuators from conducting IPNs architecture are described. The electroactive materials are based on several PEO/elastomer IPNs as solid polymer electrolytes in which the conducting polymer Poly(3,4-ethylenedioxythiophene) (PEDOT) is gradually dispersed, i.e. its content decreases from the outside…
