Interface-driven giant piezoelectric enhancement in ScN/AlN bilayers and its comparison with Sc0.5Al0.5N alloys under epitaxial strain: A first-principles study

Imene Cherair, Abdelkrim El Hadi Khediri, Ali Soltani

We present a comparative first-principles study of and alloys, as well as wurtzite ScN/AlN and GaN/AlN bilayers, focusing on their piezoelectric and elastic properties under epitaxial strain. Our results reveal a dramatic enhancement of the out-of-plane piezoelectric response in ScN/AlN bilayers…

Measurement of magnetic loss in ferromagnetic lamella using high sensitivity piezo-magnetic surface acoustic wave sensor

Othmane Marbouh, Gaétan Sanchez, Aurelien Mazzamurro, Mohamed Boutghatin, Olivier Bou Matar, Yannick Dusch, Romain Viard, Aymen Ammar, Philippe Pernod, Nicolas Tiercelin, Abdelmounaim Tounzi, Abdelkader Benabou, Abdelkrim Talbi

Magnetic field sensors combining surface acoustic waves (SAW) and magnetostrictive thin films have shown promising sensitivity in laboratory studies, but their translation into real-world applications has remained limited. In this work, we report the first practical deployment of a shear-horizontal…

Beyond the Spectrum: Measuring More Than Microwave Sensors [Women in Microwaves]

Siti Amalina Enche Ab Rahim, Zuhani Ismail Khan, Megat Syahirul Amin Megat Ali, Nor Ayu Zalina Zakaria, Kamel Haddadi

When I first began my journey in microwave engineering, I never imagined how far it would take me, not only across technologies but across borders, disciplines, and perspectives. What started as a fascination with resonators and circuits has evolved into a journey that connects people, ideas, and…

Les isolants topologiques constituent une classe de matériaux périodiques caractérisés par des propriétés topologiques intrinsèques permettant un contrôle particulier de la propagation des ondes. Initialement développés dans le contexte des systèmes quantiques électroniques, ces concepts ont…, Topological insulators constitute a class of periodic materials characterized by intrinsic topological properties that enable enhanced control over wave propagation. Initially developed in the context of quantum electronic systems, these concepts have subsequently been extended to artificial…

Experimental and mathematical models reveal that AMPK modulates circadian clock gene expression and period through NAD+-dependent regulation of Bmal1

Alan Vandenberghe, Pauline Delpierre, Raoul Torero-Ibad, Pierre Leclerc, Anthony Treizebre, Alexandre Berthier, Laurent Heliot, Helene Duez, Bart Staels, Philippe Lefebvre, Alessandro Furlan, Marc Lefranc

The circadian clock allows living systems to anticipate environmental daily variations by scheduling cellular mechanisms according to the time of the day. The reciprocal interplay between metabolism and circadian clock is essential for energy homeostasis, and the disruption of metabolic clock…

Bragg resonator cavity for time-resolved microwave conductivity measurement

Ali Ghaddar, M. Boutghatin, Patrick Ropa, M. Toufaily, Bator Khol, Sebastien Saitzek, Jean-François Blach, N. Tentillier, Redouane Douali

Time-resolved microwave conductivity (TRMC) is a well-established technique for characterizing charge carriers in materials. This technique relies on a sensitive resonant microwave cavity to detect small changes in the material’s conductivity induced by a laser pulse. Conventional TRMC systems…

Disorder‐Assisted Topological States and Critical Couplings in Continuous Elastic Metaplates

Runcheng Cai, Minle Yu, Yabin Jin, Bahram Djafari-Rouhani, Yanxun Xiang, Xiaoying Zhuang, Timon Rabczuk

ABSTRACT Precise manipulation of elastic waves in continuous solid‐state media is important for enhancing wave‐matter interactions and enabling applications such as energy harvesting, nondestructive testing, sensing, and on‐chip signal processing. Disorder is typically regarded as detrimental to…
