Directional Acoustic Bulk Waves in a 2D Phononic Crystal

Pierre A Deymier, Jérôme O Vasseur, Keith Runge, Krishna Muralidharan, Alexander Khanikaev, Andrea Alù

We used the transfer matrix method to investigate the conditions supporting the existence of directional bulk waves in a two-dimensional (2D) phononic crystal. The 2D crystal was a square lattice of unit cells composed of rectangular subunits constituted of two different isotropic continuous media...

High Capacitance Porous Ruthenium Nitride Films with High Rate Capability for Micro‐Supercapacitors

Khac Huy Dinh, Grace Whang, Marielle Huve, David Troadec, Antoine Barnabé, Bruce Dunn, Pascal Roussel, Christophe Lethien

The demand for high-performance energy storage devices to power Internet of Things applications has driven intensive research on micro-supercapacitors (MSCs). In this study, RuN films made by magnetron sputtering as an efficient electrode material for MSCs are investigated. The sputtering...

Detection and imaging of BVIDs in composite plates

Pierre Goislot, Guillemette Ribay, Emmanuel Moulin, Lynda Chehami

Composite materials are increasingly used in the aerospace industry. However, they may be subjected to Barely Visible Impact Damages (BVIDs). BVIDs can occur during maintenance phases or during flight and are almost impossible to detect with the naked eye. Although very small, these defects greatly...

Exploring the properties of higher-order Tamm plasmons for liquid and gas detection

O. Haidar, Baptiste Mathmann, Y. Dusch, Mohamed Boutghatin, E. Boudouti, G. Lévêque, A. Mir, A. Akjouj, A. Talbi

In this study, we present a numerical analysis of the higher-order Tamm plasmons for the design of a gas and liquid sensor. These plasmons are induced by a structure consisting of a cavity placed between the SiO2/Si3N4 Bragg grating and a finite layer of gold. This configuration is excited without...

Enhancing Tamm Plasmon Sensor Performance using Nanostructured Gold Grating and Porous Materials

O. Haidar, Baptiste Mathmann, Yannick Dusch, Mohamed El Barghouti, Romain Viard, Gaëtan Lévêque, El Houssaine El Boudouti, Abdellah A. Mir, A. Talbi, Abdellatif Akjouj

In this paper, we introduce a gas sensor concept consisting of a nanostructured gold grating coupled with a Distributed Bragg Reflector. This coupling makes it possible to obtain plasmonic Tamm states where excitation is possible at normal incidence and does not require the use of Kretschmann...

An Incremental Time-Domain Mixed-Signal Matrix-Vector-Multiplication Technique for Low-Power Edge-AI

Kévin Hérissé, Benoit Larras, Bruno Stefanelli, Andreas Kaiser, Antoine Frappé

This paper proposes a time-domain mixed-signal computing architecture for Matrix-Vector Multiplication suited for embedded in-memory computing applications. The system leverages the low data rate of sensors’ data in embedded AI applications to target an energy-efficient implementation of the matrix...

Continuously Beam-Steered Phased Array Antenna Using GaN Varactors for Millimeter-Wave Applications

Abdelaziz Hamdoun, F Medjdoub, Mohamed Himdi, Malek Zegaoui, Olivier Lafond

A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here, the GaN HEMTs are used as varactor diodes to achieve the tunability purpose. By controlling the DC bias of these varactors from −2 V to 2 V, the proposed array antenna can...
