High Power AlN/GaN HEMTs with record power-added-efficiency >70% at 40 GHz

Kathia Harrouche, Riad Kabouche, Etienne Okada, F Medjdoub

We report on breakthrough power-added-efficiency (PAE) Q-band performances using a vertically scaled AlN/GaN HEMT technology. The comparison between a 3 nm and 4 nm barrier thickness shows both superior performance and robustness for the thinner barrier layer attributed to the reduced mechanical…

Evaluation of micro laser sintering metal 3D-printing technology for the development of waveguide passive devices up to 325 GHz

Victor Fiorese, Cybelle Belem-Gonçalves, Carlos del Rio, Diane Titz, Frédéric Gianesello, Cyril Luxey, Guillaume Ducournau, Emmanuel Dubois, Christophe Gaquière, Daniel Gloria

In this paper, we propose an assessment up to 325 GHz of Micro Laser Sintering (MLS) metal 3D-Printing technology in order to achieve lightweight and cost-effective millimeter wave (mmW) passive function. We first designed and manufactured a bended WR5 waveguide in order to assess achievable…

Vertical multilayer structures based on porous silicon layers for mid-infrared applications

Warda Raiah, Yannick Coffinier, V. Thomy, Maxime Duris, Mohammed Guendouz, Nathalie Lorrain, Parastesh Pirasteh, Loïc Bodiou, Joël Charrier

In this work, the fabrication of a porous silicon Bragg reflector and vertical cavity on P+ silicon substrate is investigated for applications in spectroscopic sensing in the mid-infrared (Mid-IR) wavelength range. The complex refractive index of porous silicon layers is measured. Optical vertical…

Elastic stubbed metamaterial plate with torsional resonances

Wei Wang​, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec, Jinfeng Zhao

We report on a new mechanism involving the torsional resonance of stubs to achieve the negative effective shear modulus of an elastic metamaterial plate. Combined with a mechanism to create a negative mass density, we develop a general method to set up and enlarge a shear-horizontal-polarized…

Broadband Asymmetric Propagation in Pillared Meta-Plates

Lin Chen, Wei Wang​, Guohua Nie, Yabin Jin, Daniel Torrent, Bahram Djafari-Rouhani

The asymmetric propagation of mechanical energy across interfaces is a challenging problem with a wide range of applications. In this work, we present a novel structure presenting the asymmetric propagation of elastic waves in thin plates in a broadband range. The structure consists of a…

Textile NFC antenna for power and data transmission across clothes

Baptiste Garnier, Philippe Mariage, Francois Rault, Cedric Cochrane, Vladan Koncar

In this article, it is shown how a smartphone can be used together with an e-textile structure, such as smart clothing, or any other smart home textile structure, smart composite, etc, to power it and to send and receive data generated by the e-textile by using the magnetic induction phenomenon…

The antimicrobial peptide oranicin P16 isolated from Trichosporon asahii ICVY021, found in camel milk's, inhibits Kocuria rhizophila

Soufian Ider, Yanath Belguesmia, Guillaume Cazals, Rabah Boukherroub, Françoise Coucheney, Mabrouk Kihal, Christine Enjalbal, Djamel Drider

Six Trichosporon asahii strains designated ICVY021, ICVY022, ICVY023, ICVY024, ICVY025 and ICVY026 were isolated from camel milk and studied for their inhibitory activities against a large number of fungi and bacteria as target organisms. Only strain ICVY021 was able to inhibit Kocuria rhizophila…

2-D Modeling of Rosen-Type Piezoelectric Transformer by Means of a Polynomial Approach

Derandraibe Jeannot Falimiaramanana, Faniry Emilson Ratolojanahary, Jean-Etienne Lefebvre, Lahoucine El Maimouni, Mohamed Rguiti

A 2-D semianalytical model using the Legendre polynomial approach was applied for modeling the piezoelectric transformer (PT). In the model, the mechanical displacements and the electric potential were expanded in a double series of orthonormal polynomials with an appropriate analytical form.…
