Finite Element Method (FEM) simulations are vital in the design of loudspeakers, providing an efficient alternative to traditional trial-and-error methods. This study aims to advance the understanding and optimization of loudspeaker design focusing particularly on the influence of ... En savoir plus

This work reports the application of topology optimization for the design of two types of metallic antennas that are very different from each other: a leaky-wave antenna (LWA) radiating at broadside, and an epidermal patch antenna, optimized to favor radiation coupling into the human ...

As part of its research, the Group of Electrical Engineering-Paris (GeePs) uses COMSOL Multiphysics software for applications such as material modelling in Electrical Engineering, electromagnetic compatibility and Eddy current non-destructive testing (EC-NDT). EC-NDT is an easy-to-use ... En savoir plus

Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... En savoir plus

In the context of climate change mitigation, hydrogen represents a promising and versatile energy vector. Water electrolysis powered by renewable energy offers a sustainable method for hydrogen production, with efficiency gains achievable at the higher operating temperatures of Solid ... En savoir plus

Foundation scour is a major cause of bridge collapse worldwide (e.g., Kirby et al., 2015). Indeed, several studies have demonstrated its detrimental effects on the soil-structure system, both in terms of the foundation capacity and stiffness (e.g., Foti et al., 2023). Furthermore, the ...

Polydimethylsiloxane (PDMS) is a biocompatible material widely used in biomedical applications such as implantable sensors. A realistic modeling of PDMS in acoustic-mechanic simulation is useful especially for medical applications which use ultrasonic waves as interrogation source. ... En savoir plus

The protection of metal surfaces against corrosion is commonly achieved by the application of organic coatings. A dedicated evaluation of those coating systems is strictly necessary before putting them into service. While outdoor test programs are time intensive and accelerated corrosion ... En savoir plus

Multilayer transition metal dichalcogenides (TMDCs) are an emerging class of dielectric materials with promising applications in modern nanophotonics. They exhibit a much higher refractive index (~ 4 - 4.5) than traditional semiconducting materials like Silicon (~ 3.5) in the near ... En savoir plus
