Nano-particle mass sensing using phononic pillars

Bonhomme Jeremy, Oudich Mourad, Bahram Djafari-Rouhani, Sarry Frederic, Yan Pennec, Bonello Bernard, Beyssen Denis, Paul Charette

In this work, we investigate the sensitivity of a pillar based metasurface in order to understand the behavior of the system in real tests conditions where the mass perturbation will not be homogeneous on all the system. The structure we study is composed in stacking alternate layers of Silica and…

Plasmon induced transparency in graphene-based side coupled two rectangular nano-cavities-like structures

A. Noual, M. Amrani, E.H. El Boudouti, Yan Pennec, Bahram Djafari-Rouhani

We investigate numerically the plasmon analogue of electromagnetic induced transparency (EIT) in a compact graphene-based waveguide coupled to two rectangular nano-cavities-like structures made out of graphene nanoribbons. The cavities are placed symmetrically on each side of the bus waveguide,…

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…

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…

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…

Optimal power allocation in a relay-aided cognitive network

Anne Savard, E. Veronica Belmega

In this paper, we address a power allocation problem in a relay-aided cognitive network. The network is composed by a primary and secondary user/ destination pair and a relay, which helps the communication between the secondary user and its destination. The transmission of the secondary user and…
