Dynamics of the stress-mediated magnetoelectric memory cell N×(TbCo2/FeCo)/PMN-PT

Vladimir Preobrazhensky, Alexey Klimov, Nicolas Tiercelin, Yannick Dusch, Stefano Giordano, Anton Churbanov, Theo Mathurin, Philippe Pernod, Alexander Sigov

Stress-mediated magnetoelectric heterostructures represent a very promising approach for the realization of ultra-low energy Random Access Memories. The magnetoelectric writing of information has been extensively studied in the past, but it was demonstrated only recently that the magnetoelectric…

Thermal conductivity of deca-nanometric patterned Si membranes by multiscale simulations

Hayat Zaoui, Pier Luca Palla, Stefano Giordano, Fabrizio Cleri, Maxime Verdier, David Lacroix, J.F. Robillard, Konstantinos Termentzidis, Évelyne Martin

The hollowing of silicon membranes to form a lattice of cylindrical holes, also called phononic crystal, has been used by several experimental groups willing to fabricate efficient thermoelectric modules. The idea is to reduce the thermal conductivity without impacting the electronic conductivity.…

Unambiguous real-time terahertz frequency metrology using dual 10 GHz femtosecond frequency combs

Oliver Kliebisch, Dirk Heinecke, S Barbieri, Giorgio Santarelli, Hua Li, Carlo Sirtori, Thomas Dekorsy

Terahertz frequency metrology by radio frequency downconversion using femtosecond optical sampling relies on the harmonic factor retrieval between the terahertz frequency and the optical sampling rate. At typical femtosecond laser repetition rates, this imposes an ambiguity for frequency metrology…

Low-complexity feature extraction unit for “Wake-on-Feature” speech processing

Simon Lecoq, Jean Le Bellego, Angel Gonzalez, Benoit Larras, Antoine Frappé

In the context of energy-constrained automatic speech recognition, a modeling and simulation tool is presented to evaluate the hardware complexity of a feature extraction unit. The objective is to evaluate the minimal amount of features necessary for voice-activity detection, considering limited…

High-Pass Sub-mm Wave Filtering by Woven Textile Metamaterials

Ludovic Burgnies, Camille Huppe, Guillaume Ducournau, Cedric Cochrane, Francois Rault, Vladan Koncar, Eric Lheurette

Textile metamaterials produced by a weaving of metallic and dielectric yarns are considered for filtering operations in the sub-millimeter hand. A woven metamaterial was designed by parametric simulations aimed at producing a high-pass filter with a cutoff frequency at around 500 GHz above a high-…

The role of dispersion forces on the atomic structure of glassy chalcogenides: The case of GeSe4 and GeS4

Ziyad Chaker, Guido Ori, Christine Tugène, Sébastien Le Roux, Mauro Boero, Carlo Massobrio, Évelyne Martin, Assil Bouzid

Recent first-principles molecular dynamics simulations (FPMD) results on two chalcogenide glasses (glassy GeS4 and GeSe4) are revisited by accounting explicitly for van der Waals (vdW) dispersion forces. This effort is motivated by the observation that such contributions were found to be important…

Phononics

L. Dobrzynski, El Houssaine El Boudouti, Abdellatif Akjouj, Yan Pennec, Housni Al-Wahsh, Gaëtan Lévêque, Bahram Djafari-Rouhani

Phononics: Interface Transmission Tutorial Book Series provides an investigation of modern systems that includes a discrete matrix description. Classical continuous systems relying on the use of differential equations are recalled, showing that they generally have a specific limit on their…

Acoustic analogue of electromagnetically induced transparency and Autler-Townes splitting in pillared metasurfaces

Yabin Jin, Yan Pennec, Bahram Djafari-Rouhani

Electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) originating from multilevel atomic systems have similar transparency windows in transmission spectra which causes confusion when discriminating between them, despite the difference in their physical mechanisms. Indeed…

Rayleigh Waves in Phononic Crystal Made of Multilayered Pillars: Confined Modes, Fano Resonances, and Acoustically Induced Transparency

M. Oudich, Bahram Djafari-Rouhani, B. Bonello, Yan Pennec, S. Hemaidia, F. Sarry, D. Beyssen

We present a design of phononic crystal based on pillars distributed on a substrate surface in which each pillar is constructed by a periodic stacking of PMMA and silicon layers. The pillar behaves like a one-dimensional phononic crystal which allows the creation of band gaps that prohibits wave…
