As part of its research, the Group of Electrical Engineering Paris (GeePs) uses the COMSOL Multiphysics® software for applications in an Electrical Engineering context. At present, a multitude of problems, such as artificial intelligence and the database generation that goes with it, ... Mehr lesen
An "electroacoustic absorber" is a loudspeaker, used as an absorber of sound, which acoustic impedance can be varied by electrical means. This can be achieved either by plugging passive shunt electric networks at the loudspeaker terminals ("shunt loudspeakers") or by feeding back the ... Mehr lesen
The paper describes how the fluxgate current sensor works and how it is built in the COMSOL Multiphysics® software. Four COMSOL® modules were used: -AC/DC Module: the magnetic field physic is used in order to apply the Ampere-Maxwell’s law to the different sensor components and to the ... Mehr lesen
Product lifetime prediction is a crucial task in microelectronics design and fabrication. Understanding of the underlying processes causing material degradation and product failure is essential for establishing accurate lifetime models. This work aims to investigate and model the ... Mehr lesen
When studying the behavior of a MEMS or electret microphone it is important to consider the design of the inlet or sound channel (tube) that defines how the acoustic signal gets into the microphone, as well as the design of other internal acoustic components such as acoustic chambers and ...

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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
