Quadratic detection-based millimeter-wave MMIC for wireless communication and localization

Christophe Loyez, Michael Bocquet, Kamel Haddadi

This paper presents a multi-functional topology of a monolithic microwave monolithic integrated circuit (MMIC) capable of performing both wireless communications and geolocation devices. The architecture of this MMIC allows several RF functionalities such as conventional frequency heterodyning for...

Numerical modeling of a nonlinear resonant vibrometry experiment for crack imaging

Vladislav Aleshin, Ravi Verma, Kevin Truyaert

In this communication we describe an original approach to numerical modeling for acoustic waves in a solid structure with a crack. The method allows us simulating the conditions of a real acoustic experiment for non-destructive testing and damage visualization. The presence of damage, for instance...

Roll-to-roll in-line implementation of microwave free-space non-destructive evaluation of conductive composite thin layer materials

Grigorios Koutsoukis, Ivan Alic, Antonios Vavouliotis, Ferry Kienberger, Kamel Haddadi

A free-space microwave nondestructive testing and evaluation module is developed for the low-power, non-ionizing, contactless, and real-time characterization of doped composite thin-film materials in an industrial context. The instrumentation proposed is built up with a handled vector network...

Experimental Investigation of the Parameters Influencing the Surface Defect Detection by Using the Critically Refracted Longitudinal Waves

Wahiba Djerir, Mohamed Ourak, Tarek Boutkedjirt

Abstract: The aim of this work is the detection of surface defects by the refracted longitudinal wave and the study of the parameters that influence the use of this wave in transmission and reflection modes in order to optimize the non-destructive testing (NDT) conditions with the LCR waves. For...

Dynamic thermoregulatory photonic crystal fabric for personal thermal management

Mohamed Boutghatin, Yan Pennec, Salim Assaf, Michèle Carette, V. Thomy, Abdellatif Akjouj, Bahram Djafari-Rouhani

Personal thermal management represents a new paradigm to reduce the energy consumption, which consists in controlling the temperature around the human body rather than regulating the temperature of the entire residential space. Recent progress in smart textile showed promising radiative heating and...

Energy-efficient 1-bit feedback NOMA in wireless networks with no CSIT/CDIT

Hajar El Hassani, Anne Savard, E Veronica Belmega

In this paper, the energy efficiency of a two-user downlink non-orthogonal multiple access (NOMA) system is investigated. We consider a stochastic time-varying channel that is unknown at the transmitter side (in state and distribution) and propose an online learning method that is energy efficient...
