Optimization and Comparison between the efficiency of GaNAsSb and GaInNAs single solar cells deposed on GaAs

Wafa Bellil, Abdelkader Aissat, Jean-Pierre Vilcot

In this work we study and optimize the single solar cell efficiency of GaNxAs1-x-ySby and Ga1-xInxNyAs1-y deposed on GaAs. The solar cells are simulated, in the aim to find the best concentration of nitrogen and antimony for GaNxAs1-x-ySby, and indium and nitrogen for Ga1-xInxNyAs1-y which gives us…

A method to determine wide bandgap power devices packaging interconnections

Loris Pace, N. Defrance, Jean-Claude de Jaeger, Arnaud Videt, Nadir Idir

Wide Bandgap (WBG) power devices show very good characteristics for high frequency operation in power converters, leading to a better power integration by reducing size and weight of passive components. Access parasitics such as resistances and inductances related to packaging and interconnections…

Accuracy of Green's function estimation from correlation of diffuse elastic waves on thin plates

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada

In a reverberant cavity, when a noise field is sufficiently diffuse, the correlation of the signal measured by two sensors provides an estimation of the Green's function (GF) between them. Here, the convergence of this passive estimation in the case of elastic waves on thin plates is studied.…

300 GHz wireless communication systems exploiting the benefits of combining photonic and electronic transceiver components

I Kallfass, I Dan, P. Szriftgiser, V Chinni, Mohammed Zaknoune, Guillaume Ducournau

The contribution presents a wireless data transmission experiment combining photonic and electronic technologies. The photonic transmitter is based on the use of unitraveling-carrier (ETC) photodiodes. The electronic receiver is based on multi-functional monolithic integrated circuits realized in…

Performance Evaluation of Massive MIMO with Beamforming and Non Orthogonal Multiple Access based on Practical Channel Measurements

Eric Pierre Simon, Joumana Farah, Pierre Laly

This paper presents a comprehensive performance analysis of a massive multiple-input multiple-output (MIMO) system using non-orthogonal multiple access (NOMA) in both indoor and outdoor environments, based on practical channel measurements. The latter are performed using frequency-domain channel…

Conversion between surface acoustic waves and guided modes of a quasi-periodic structured nanobeam

Alexander V Korovin, Yan Pennec, Matteo Stocchi, Davide Mencarelli, Luca Pierantoni, Tapani Makkonen, Jouni Ahopelto, Bahram Djafari-Rouhani

The generation of acoustic waves in structured nanobeams containing optomechanic cavities is a topic of current interest. In this paper, we theoretically study the efficient conversion of surface acoustic waves (SAW) generated on a substrate by an RF electric signal into the acoustic waves of a…

Non-Binary Serial Turbo LDPC Codes Combined with High Order Constellations

Latifa Mostari, Abdelmalik Taleb-Ahmed

Given the increasing number of applications requiring high data transmission, this is the reason for the use of high order constellations such as Quadrature Amplitude Modulation (QAM). However, communication systems using QAM require a high signal to noise ratio. To overcome this disadvantage, it…
