Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth...

Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

Mireille Cuniot-Ponsard, Irma Saraswati, S.-M. Ko, Mathieu Halbwax, Y.-H. Cho, N.-R. Poespawati, El Hadj Dogheche

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN...

UWB System Based on the M-OAM Modulation in IEEE.802.15.3a Channel

Khadija Hamidoun, Raja Elassali, Yassin El Hillali, Khalid Elbaamrani, Atika Rivenq, F. Elbahhar

Known for many years but unexploited in the field of communications, ultra wideband systems (UWB) can be a solution to the saturation of the frequency bands. The advantage of such systems is that they are inexpensive in energy because of the limitations imposed by the standard. Our work is to...

Band gap formation and elastic wave transmission in two-dimentional surface phononic crystal

Sergey Yankin, Abdelkrim Talbi, Yu Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

Using finite element method analysis of surface acoustic wave (SAW) propagation in the phononic crystal in a form of periodic lattice from nickel pillars, located on a piezoelectric substrate of Y+128°-cut LiNbO3, has been conducted. Amplitude and phase characteristics of SAW propagation through...

High frequency acoustic for nanostructures wetting characterization

Sizhe Li, Sébastien Lamant, Julien Carlier, Malika Toubal, Pierre Campistron, Xiumei Xu, Guy Vereecke, Vincent Senez, V. Thomy, Bertrand Nongaillard

Nanostructure wetting is a key problem when developing superhydrophobic surfaces. Conventional methods do not allow us to draw conclusions about the partial or complete wetting of structures on the nanoscale. Moreover, advanced techniques are not always compatible with an in situ, real time,...

Cyclones and attractive streaming generated by acoustical vortices

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Olivier Bou Matar

Acoustical and optical vortices have attracted great interest due to their ability to capture and manipulate particles with the use of radiation pressure. Here we show that acoustical vortices can also induce axial vortical flow reminiscent of cyclones, whose topology can be controlled by adjusting...
