Development of the multi-quantum wells structures based on InxGa1-x As1-yNy/GaAs for solar cells applications

Abdelkader Aissat, Rachid Bestam, Manel Boubakeur, Jean-Pierre Vilcot

In order to improve the solar cell efficiency, quantum multi-wells have been implanted into the intrinsic region of the structure. We can absorb the photons that have a lower energy than the bandgap energy. In this work, physical and optical phenomena that influence the efficiency of the solar cell...

Design of orthogonal filter banks using a multi-objective genetic algorithm for a speech coding scheme

Abdelkader Boukhobza, Nasreddine Taleb, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

In this work, we propose an optimization scheme based on a multi-objective Genetic Algorithm (GA) for the design of orthogonal filter banks for speech compression. A parameterization is adopted to assure that the resulting filter banks satisfy perfect reconstruction and have at least two vanishing...

Broadband 3-D Shared Aperture High Isolation Nine-Element Antenna Array for On-Demand Millimeter-Wave 5G Applications

Mohammad Alibakhshikenari, Bal Virdee, Valeria Vadalà, Mariana Dalarsson, María Elena de Cos Gómez, Abdullah Alharbi, Shah Nawaz Burokur, Sonia Aïssa, Iyad Dayoub, Francisco Falcone, Ernesto Limiti

The paper presents the results of a novel 3-D shared aperture 3×3 matrix antenna-array for 26 GHz band 5 G wireless networks. Radiation elements constituting the array are hexagonal-shaped patches that are elevated above the common dielectric substrate by 3.35 mm and excited through a metallic rod...

Metasurface-based Filters for High Data Rate THz Wireless Communications: Experimental Validation of a 14 Gbps OOK and 104 Gbps QAM-16 Wireless Link in the 300 GHz band

D. Pirrone, A. Ferraro, D. Zografopoulos, W. Fuscaldo, P. Szriftgiser, Guillaume Ducournau, R. Beccherelli

We demonstrate the effectiveness of frequency selective surface filters in wireless communications at low terahertz (THz) frequencies. Full-wave simulations of pass-band filters designed at 270 GHz and 330 GHz are compared with measurements over 220–360 GHz, showing remarkable agreement. The filter...

Dispersion of surface acoustic waves in thin films at extreme wavelength-to-thickness ratios

Marc Duquennoy, Tahar Kadi, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Jenot

Surface acoustic waves (SAWs) are sensitive to the presence of a layer on the surface of a material, even if this layer is extremely thin compared to their wavelengths. Given the very slow propagation velocities of SAWs compared to electromagnetic waves, their wavelengths are on the order of 40 μm...

CNTFET‐based ternary address decoder design

Rawan Mohammed, Mohammed Fouda, Ihsen Alouani, Lobna Said, Ahmed Radwan

With the end of Moore's law, new paradigms are investigated for more scalable computing systems. One of the promising directions is to examine the data representation toward higher data density per hardware element. Multiple valued logic (MVL) emerged as a promising system due to its...

Influence of graphene oxide on the toxicity of polystyrene nanoplastics to the marine microalgae Picochlorum sp.

Gamze Yesilay, Layla Hazeem, Mohamed Bououdina, Demet Cetin, Zekiye Suludere, Alexandre Barras, Rabah Boukherroub

Graphene oxide (GO) features distinctive physical and chemical characteristics; therefore, it has been intensively investigated in environmental remediation as a promising material for clean-up of soil contamination and water purification and used as immobilization material. Plastic is a widespread...

Acoustic Sensor Based on a Cylindrical Resonator for Monitoring a Liquid Flow

Abdellatif Gueddida, Yan Pennec, Ana Luiza Silveira Fiates, Michael Johannes Vellekoop, Bernard Bonello, Bahram Djafari-Rouhani

We present a numerical investigation of an acoustic sensor based on a cylindrical resonator to monitor the acoustic properties of liquids flowing in a tube. The sensor design consists of a hollow cylindrical washer surrounding the tube, which carries the liquid, and which can be filled during the...
