Optomechanic Coupling in Ag Polymer Nanocomposite Films

Adnane Noual, Eunsoo Kang, Tanmoy Maji, Manos Gkikas, Bahram Djafari-Rouhani, George Fytas

Particle vibrational spectroscopy has emerged as a new tool for the measurement of elasticity, glass transition, and interactions at a nanoscale. For colloid-based materials, however, the weakly localized particle resonances in a fluid or solid medium renders their detection difficult. The strong…

An advanced ageing methodology for robustness assessment of normally-off AlGaN/GaN HEMT

F. Albany, A. Curutchet, N. Labat, F. Lecourt, E. Walasiak, H. Maher, Y. Cordier, N. Defrance, N. Malbert

The semi-on-state reliability of normally-off AlGaN/GaN high electron mobility transistor fabricated by fluorine ion plasma implantation technology is reported, focusing on an advanced dc step-stress methodology. By inserting a non-stressful fixed-bias step between each stress step, a reliable in-…

The Map3k12 (Dlk)/JNK3 signaling pathway is required for pancreatic beta-cell proliferation during postnatal development

Mathie Tenenbaum, Valérie Plaisance, Raphael Boutry, Valérie Pawlowski, Cécile Jacovetti, Clara Sanchez-Parra, Hélène Ezanno, Julien Bourry, Nicole Beeler, Gianni Pasquetti, Valery Gmyr, Stéphane Dalle, Julie Kerr-Conte, François Pattou, Syu-Ichi Hirai, Romano Regazzi, Amélie Bonnefond, Philippe Froguel, Amar Abderrahmani

Unveiling the key pathways underlying postnatal beta-cell proliferation can be instrumental to decipher the mechanisms of beta-cell mass plasticity to increased physiological demand of insulin during weight gain and pregnancy. Using transcriptome and global Serine Threonine Kinase activity (STK)…

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine…

Surface modes in plasmonic stubbed structures

Y. Rezzouk, M. Amrani, S. Khattou, E.H. El Boudouti, Bahram Djafari-Rouhani

We present an analytical and numerical study about the existence of surface localized modes, known as Tamm states, in a one-dimensional (1D) comb-like plasmonic band gap structure. Surface plasmon polaritons (SPPs) waveguides with coupled resonators have been widely studied in recent years, because…

Plasmonic demultiplexer based on induced transparency resonances: Analytical and numerical study

E.H. El Boudouti, Bahram Djafari-Rouhani, M. Amrani, S. Khattou, A. Noual

We study both analytically and numerically the possibility to realize a simple plasmonic Y-shaped demultiplexer made of an input line and two output lines. Each line consisting of a metal-insulator-metal (MIM) waveguide contains a specific resonator made of two stubs grafted at a given position…

Induced transparency based subwavelength acoustic demultiplexers

T. Gu, Y. Cheng, Z. Wen, E.I.H. Ei Boudouti, Y. Jin, Y. Li, Bahram Djafari-Rouhani

Wave demultiplexers transporting desired wavelengths towards proper directions or ports are attracting numerous interests and applications in both physical and engineering areas. In acoustics, there is still a lack of compact and simple designs to achieve demultiplexers in three-port systems. In…
