Experimental Characterization of A Piezoelectric Transducer Array Taking into Account Crosstalk Phenomenon

Abdelmajid Bybi, Driss Khouili, Christian Granger, Mohammed Garoum, Ahmed Mzerd, Anne-Christine Hladky

Ultrasonic transducer arrays are generally composed of several piezoelectric elements arranged in 1D or 2D ways. Crosstalk is an undesirable phenomenon decreasing the performance of these devices. It generates parasitic displacements at the elements' radiating surfaces, which changes the…

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 (…

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…

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…

Near-field measurement and far-field characterization of a J-band antenna based on an electro-optic sensing

Shintaro Hisatake, Yusuke Tanaka, Cybelle Belem-Gonçalves, Cyril Luxey, Frédéric Gianesello, Guillaume Ducournau, Akihiko Hirata

In this paper, we present a near-field pattern measurement based on an electro-optic sensing at 300 GHz band. The measurement system is based on a self-heterodyne technique and non-polarimetric frequency down-conversion technique. The far-field radiation pattern of a horn antenna calculated from…

Application of the GPR and ERT methods for non-invasive examination of a flood dike

Tomislaw Golebiowski, Bogdan Piwakowski, Michal Cwiklik

As part of the NAWA-EMMAT project, geophysical surveys were carried out on selected sites in Poland, i.e. on the flood dike and in the surrounding of the concrete water dam. The goal of the surveys was the non-invasive detection of loose zones in the flood dike and fractured zones located in the…
