An optical power divider based on mode coupling using GaN/Al2O3 for underwater communication

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, Tomy Abuzairi, El Hadj Dogheche

This paper details the design of a 1 \texttimes 8 optical power divider, using a gallium nitride (GaN) semiconductor on sapphire, which can be applied to underwater optical wireless communication. The design consists of nine parallel rectangular waveguides which are based on mode coupling phenomena…

Electromagnetic physical modeling of a gallium nitride distributed transferred electron device based planar waveguide structure THz oscillator

Christophe Dalle

The potential of a planar waveguide structure terahertz oscillator based on a gallium nitride distributed transferred electron device is theoretically investigated. The circuit numerical physical modeling relies on a two-dimensional time-domain electromagnetism/transport simulator. It is based on…

Multiple antenna receiver under impulsive SαS noise

Nicolas de Araujo Moreira, Laurent Clavier

In a usual MIMO framework when noise is assumed Gaussian, the channel matrix can be estimated with a Least Square approach. In addition, the Euclidean distance is optimal to detect the transmitted symbol. However, in dynamic interference, the Gaussian assumption is no longer valid. In this case,…

Plasmon-Induced Electrocatalysis with Multi-Component Nanostructures

Palaniappan Subramanian, Dalila Meziane, Robert Wojcieszak, Franck Dumeignil, Rabah Boukherroub, Sabine Szunerits

Noble metal nanostructures are exceptional light absorbing systems, in which electron–hole pairs can be formed and used as “hot” charge carriers for catalytic applications. The main goal of the emerging field of plasmon-induced catalysis is to design a novel way of finely tuning the activity and…

High performance and highly robust AlN/GaN HEMTs for millimeter-wave operation

Kathia Harrouche, Riad Kabouche, Etienne Okada, F Medjdoub

We report on a 3 nm AlN/GaN HEMT technology for millimeter-wave applications. Electrical characteristics for a 110 nm gate length show a maximum drain current density of 1.2 A/mm, an excellent electron confinement with a low leakage current below 10 μA/mm, a high breakdown voltage and a F T /F max…

22nm ultra-thin body and buried oxide FDSOI RF noise performance

Ousmane Kane, Luca Lucci, Pascal Scheiblin, Sylvie Lepilliet, Francois Danneville

The drastic downscaling of the transistor size along with advances in material sciences allowed the development of low power CMOS technologies with competitive RF figure of merits suitable for millimeter applications. In this context, this paper presents the RF and noise characterization (up to 110…

Modeling of An Obstacle Detection Chain in A Vehicular Environment

D. Daghouj, Said Mazer, Y. Balboul, Atika Rivenq, Laila Sakkila

This article focuses on the modeling of the different parts of an ultra-wideband (UWB) transmission chain for detecting vulnerable people on the road by using a monocycle pulse with a very short width of about 0.3 nanoseconds at emission, a coherent receiver based on the correlation of the received…

Wide Band (0,5-67 GHz) Dielectric Properties of Biosourced Cellulose Ester Flexible Films

S.M. Li, Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, T. Lasri

In this work, the dielectric properties of a biosourced polymer are investigated. To that end, coplanar transmission lines were fabricated on a 600 μm thick cellulose palmitate substrate by using a transfer technique and photolithography. Then, the S-parameters of the transmission lines were…

Transverse acoustic waves in piezoelectric-metallic Fibonacci multilayers

M. Alami, I. Quotane, E.H. El Boudouti, Bahram Djafari-Rouhani

We study the propagation of transverse acoustic waves in quasi-periodic structures following the Fibonacci sequence made of two blocs A and B where the block A is a metal layer and the bloc B is a piezoelectric layer. The phonon dynamics is described by coupled elastic equations within the static…
