Wireless communication link at 300 GHz with up to 160 GBit/s

S. Nellen, S. Lauck, Emilien Peytavit, P. Szriftgiser, Guillaume Ducournau, B. Globisch

We demonstrate a wireless communication link in the 300 GHz band with a maximum single channel data rate of 160 GHz achieved with QAM32 modulation at 32GBaud. To the best of our knowledge this is the highest data rate reported for a single channel in this frequency band. The system employs a…

Tunable frequency band structure in photo-responsive elastic metamaterials

A.S. S Gliozzi, M. Miniaci, A. Chiappone, A. Bergamini, F. Bosia, E. Descrovil, E Descrovi

An important issue in the field of elastic metamaterials is that their dynamic properties, such as the band gap frequencies, are typically fixed once the structure has been designed and fabricated. To overcome this limitation, many efforts have been made to conceive materials with adaptive elastic…

Non destructive auscultation and imaging of damages by distributed sensor array: step towards passive SHM under real conditions

Lynda Chehami, Emmanuel Moulin, Marina Terzi

The passive imaging based on the Green’s functions reconstruction from ambient noise correlation became a promising technique in structural health monitoring. Here, this approach is used to detect and locate linear defects (cracks, holes..) in thin reverberant plates with a small number of sensors…

Magneto-Electroacoustic Dynamics in a Straintronic Random Access Memory Cell

Vladimir Preobrazhensky, L.M. Krutyansky, Nicolas Tiercelin, Philippe Pernod

The straintronic principle of nonvolatile magnetoelectric random access memory (MELRAM) isattracting attention because of the prospect of achieving ultra-low-power consumption in memory devices onits basis. The mechanism of switching magnetic moments by pulse deformation of elastically coupled mag-…

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 (…
