Dispersion of IDT-induced high-frequency surface acoustic waves - Application to the mechanical and dimensional characterization of mesoporous silicon

Tahar Kadi, Marc Duquennoy, Katir Ziouche, Mohammadi Ouaftouh, Nikolay Smagin

A method based on the dispersion of surface acoustic waves (SAW) is proposed for the effective characterization of mesoporous silicon (MPS) layers with the possibility of estimating Young's modulus and the thickness of the porous layer, as well as the porosity. For this purpose, IDT were…

Development of PZT-based 18 MHz 2D pMUT array with PDMS waveguide

Xu-Bo Wang, Le-Ming He, Wen-Juan Liu, Shu-Ren Song, Wei-Jiang Xu, Qian Cheng, Antoine Riaud, Jun-Yan Ren, Jia Zhou

For high-resolution ultrasonic imaging, an 18 MHz lead zirconate titanate (PZT) based two-dimensional (2D) piezoelectric micromachined ultrasonic transducers (pMUTs) array with polydimethylsiloxane (PDMS) waveguide are developed. The array is composed of 8 x 16 elements with a pitch of 75 mu m and…

Atomic Structure of Glassy GeTe 4 as a Playground to Assess the Performances of Density Functional Schemes Accounting for Dispersion Forces

Pier Luigi Silvestrelli, Évelyne Martin, Mauro Boero, Assil Bouzid, Guido Ori, Carlo Massobrio

The atomic structure of glassy GeTe4 is obtained in the framework of first-principles molecular dynamics (FPMD) by considering five different approaches for the description of the electronic structure within density functional theory (DFT). Among these schemes, one is not corrected by accounting…

Multiple sequential constraint removal algorithm for channel estimation in vehicular environment

Soheyb Ribouh, Yassin El Hillali, Atika Rivenq

Since the vehicular environment is highly mobile, the transmitted messages are affected by the wireless channel effect. This makes channel estimation one of the important tasks in Vehicle-To-Everything (V2X) communications. In this paper, we propose a novel Multiple Sequential Constraint Removal (…

Characterization of 1-3 Piezocomposite Using Lamb Waves Propagation

Rémi Rouffaud, Anne-Christine Hladky, Dominique Certon, Antoine Balé, Franck Levassort

Due to their enhanced electromechanical properties with respect to conventional piezoelectric ceramics, 1-3 piezocomposite (1-3PC) materials are predominant in high performance ultrasonic array. Their complete effective electroelastic modulus (EEM) has a significant importance for numerical…

A superheterodyne 300 GHz wireless link for ultra-fast terahertz communication systems

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The…

Tunable photo-responsive elastic metamaterials

Antonio S. Gliozzi, M. Miniaci, Annalisa Chiappone, Andrea Bergamini, Benjamin Morin, Emiliano Descrovi

The metamaterial paradigm has allowed an unprecedented space-time control of various physical fields, including elastic and acoustic waves. Despite the wide variety of metamaterial configurations proposed so far, most of the existing solutions display a frequency response that cannot be tuned, once…
