Development and validation of a 2D Mason model for ultrasonic transducer arrays: A simplified approach simulating crosstalk and dissipation mechanisms

Anouar Boujenoui, Abdelmajid Bybi, Hayat Reskal, Hassna Khalfi, Lahoucine Elmaimouni, Anne-Christine Hladky-Hennion

Piezoelectric elements arranged in 1D or 2D configurations are commonly used in ultrasonic transducer arrays for medical imaging and non-destructive testing (NDT) applications. These arrays are usually modeled using complex 2D or 3D numerical methods. Based on the equivalent circuit approach...

PCB-Based Hybrid Series/Corporate-Fed 4 × 4 D-Band Phased Array With Wide-Angle Scanning

Kamil Yavuz Kapusuz, Samuel Rimbaut, Siddhartha Sinha, Joris van Driessche, Ad Reniers, A. Bart Smolders, Pascal Szriftgiser, Guillaume Ducournau, Hendrik Rogier, Sam Lemey

Sixth generation (6G) wireless networks are envisioned to include aspects of energy footprint reduction (sustainability), besides those of network capacity and connectivity, at the design stage. This paradigm change requires radically new physical layer technologies. Notably, the integration of...

FragCast: A Scalable BLE-based OTA Framework for Constrained IoT Devices

Ebenezer Djafsia Souboura, Damien Sambo, Paul Dayang, Michel Vianney Komguep, Laurent Clavier

The proliferation of constrained Internet of Things (IoT) devices requires scalable Over-the-Air (OTA) firmware update mechanisms. Conventional approaches, predominantly based on one-to-one communication such as Bluetooth Low Energy (BLE) Device Firmware Update (DFU), suffer from a scalability...

High-Sensitivity Love Wave SAW Sensors with Composite Guiding Layer and Phononic Crystal Cavity

A. Leschiutta, G. Eybert-Bouillier, Othmane Marbouh, O. Bou-Matar, V. Mortet, A. Talbi

In Love-wave-based biosensors, the most widely used architecture is the delay-line configuration, in which the sensing function is achieved by functionalizing the acoustic propagation path. This approach offers high robustness and compatibility with liquid-phase operation, making it particularly...

Structural and electronic signatures of stacking and intralayer transitions in epitaxial bilayer WSe2 on GaP(111)B

Meryem Bouaziz, Samir El Masaoudi, Aymen Mahmoudi, Niels Chapuis, Mathieu Silly, Gilles Patriarche, Iann Gerber, Julien Chaste, Fabrice Oehler, Xavier Wallart, Abdelkarim Ouerghi

Two-dimensional materials from the transition metal dichalcogenides family host multiple crystal phases and stacking configurations that strongly affect their electronic properties. Here, we investigate the structural and electronic phase evolution of epitaxial bilayer WSe2 grown by molecular beam...

Steerable Thin-Film Electrode Array for Cochlear Implantation: Design and Development for Future Atraumatic Insertion

Ahmad Itawi, Bacem Zribi, Prabhakar Sidambaram, Thanh Hang Tran, Guillaume Tourrel, Renato Torres, Sofiane Ghenna, Sébastien Grondel, Yann Nguyen, Cedric Plesse, Eric Cattan

During cochlear implant surgery, standard electrode arrays are inserted into the scala tympani to stimulate the spiral ganglion cells and rehabilitate hearing in deaf patients. However, conventional electrode arrays' stiffness and passive nature lead to potential trauma or incomplete insertion...

0.2-<i>μ</i>m InP/GaAsSb DHBT Transferred on Si-HR With 28 mW/<i>μ</i>m² at 94 GHz

Abdelmalek Zemour, Malek Zegaoui, Christophe Coinon, Yannick Roelens, Etienne Okada, Pascal Chevalier, Mohammed Zaknoune

We present 94 GHz large-signal load-pull measurements of a transferred InP/GaAsSb double heterojunction bipolar transistor fabricated on a high-resistivity silicon (Si-HR) substrate. The characterized device features an emitter area of 0.19 × 8.9 µm 2 . Biased for highest power, an output power of...
