Improved laser Ultrasonics NDT through simultaneous quasi-monochromatic and pulsed Rayleigh waves generation

Meriem Chrifi Alaoui, M. Karam, Frédéric Jenot, M. Ouaftouh, Frédéric Rivart

Laser Ultrasonics is a cutting-edge NDT solution offering a completely non-contact approach that overcomes the limits of classical ultrasonic methods. It provides high-precision spatial resolution while adapting seamlessly to complex geometries and harsh environments. Most commonly in NDT, a…

Higher-order Tamm modes in nano-structured cap layers on a distributed Bragg reflector: Application for advanced optical sensing

Oumaima Haidar, Baptiste Mathmann, Yannick Dusch, Mohamed Boutghatin, Gaëtan Lévêque, El Houssaine El Boudouti, Abdellah Mir, Abdellatif Akjouj, Abdelkrim Talbi

Tamm modes, strongly confined between a metal and a distributed Bragg reflector (DBR), offer the advantage of being accessible with conventional excitation sources, without requiring coupling elements such as prisms. Here, we experimentally observe higher-order Tamm modes in such structures by…

Bound states in the continuum in a photonic step ladder cavity

Eman Abdel-Ghaffar, Amina Rezzouk, Fatima Houari, Soufyane Khattou, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani, Housni Al-Wahsh, Leonard Dobrzyński, Abdellatif Akjouj

This paper presents an analytical study of bound states in the continuum (BICs) in a photonic step-ladder waveguide structure. We demonstrate that BICs can arise in a cavity formed by one vertical and two horizontal waveguides inserted between two semi-infinite leads. Using the Green’s function…

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…

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…
