Linear combining in dependent α-stable interference

Ce Zheng, Malcolm Egan, Laurent Clavier, Troels Pedersen, Jean-Marie Gorce

Recently, there has been a proliferation of wireless communication technologies in unlicensed bands for the Internet of Things. A key question is whether these networks can coexist given that they have different power levels, symbol periods, and access protocols. The main challenge is to…

Acoustic Tamm states in slender tubes

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Bahram Djafari-Rouhani

We present an analytical and numerical study of the possibility of existence of surface localized modes, the so-called Tamm states, in a one-dimensional (1D) comb-like phononic crystal (PnC). The structure is made out of periodic array of stubs of lengths d2grafted along a waveguide and separated…

UWB radar detection theory

Laila Sakkila, C. Tatkeu, Atika Rivenq, J. Zaidouni, Michael Bocquet

In this paper, a study of UWB receivers in terms of detection theory is presented. The UWB radar which is presented in many works previously [1]-[3] has many applications. For road UWB radar application, the receiver based on correlation is the optimum receiver [4]. In fact, it maximizes the…

Growth temperature effect on physical and mechanical properties of nitrogen rich InN epilayers

Z. Benzarti, T. Sekrafi, A. Khalfallah, Zahia Bougrioua, D. Vignaud, M. Evaristo, A. Cavaleiro

A set of N-polar InN epilayers has been grown at different temperatures by plasma-assisted molecular beam epitaxy (PA-MBE) on GaN/AlN/Al2O3(0001) templates. The purpose is to understand how the variation of crucial factor, such as the temperature, impacts the growth process and the resulting…

Bowl-shaped ZnO ultrasonic transducer for photoacoustic/ultrasonic multimode microscopy

J. Zhang, D. Zhao, D. Li, F. Tian, Wei-Jiang Xu, X. Wu

A bowl-shaped ultrasonic transducer is proposed for photoacoustic/ultrasonic multimode microscopy. The transducer uses zinc oxide (ZnO) as the piezoelectric material, which has a better electromechanical coefficient than flexible PVDF polymer and ensures the detection sensitivity. The ZnO film is…

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine…

Optomechanic Coupling in Ag Polymer Nanocomposite Films

Adnane Noual, Eunsoo Kang, Tanmoy Maji, Manos Gkikas, Bahram Djafari-Rouhani, George Fytas

Particle vibrational spectroscopy has emerged as a new tool for the measurement of elasticity, glass transition, and interactions at a nanoscale. For colloid-based materials, however, the weakly localized particle resonances in a fluid or solid medium renders their detection difficult. The strong…

A generalized deep learning-based framework for assistance to the human malaria diagnosis from microscopic images

Ziheng Yang, Halim Benhabiles, Karim Hammoudi, Feryal Windal, Ruiwen He, Dominique Collard

Malaria is an infectious disease caused by Plasmodium parasites and is potentially human life-threatening. Children under 5 years old are the most vulnerable group with approximately one death every two minutes, accounting for more than 65% of all malaria deaths. The World Health Organization (WHO…

Van Hove singularities and trap states in two-dimensional CdSe nanoplatelets

Nemanja Peric, Yannick Lambert, Shalini Singh, Ali Hossain Khan, Nathali Alexandra Franchina Vergel, D. Deresmes, Maxime Berthe, Zeger Hens, Iwan Moreels, Christophe Delerue, B. Grandidier, Louis Biadala

Semiconductor nanoplatelets, which offer a compelling combination of the flatness of two-dimensional semiconductors and the inherent richness brought about by colloidal nanostructure synthesis, form an ideal and general testbed to investigate fundamental physical effects related to the…
