Louis Demange (CY Cergy Paris Université)08/09/2026, 14:00A13 Physical Acoustics and Ultrasound
Seismogenic analogue fault models offer a novel approach for studying earthquake rupture physics at laboratory scale, enabling simulation of hundreds of seismic cycles and acquisition of data on surface deformations and radiated wavefields. Repeated rupture events occur spontaneously in a multi-layered granular medium under quasi-static shear loading, generating wavefields that carry...

Steady-state pressure field simulation, for a ultrasound transducer owing to time harmonic excitation, remains an active area of research because it provides important information regarding beam profile along the axial and lateral directions, and its convergence at the focal region and modification in the field due to scatterers etc. In this work, traditional Born series (TBS) approach has...

Microplastic management using acoustic waves, especially ultrasound, is an emerging and effective technique that utilizes radiation forces to aggregate, separate, and extract particles present in water samples. By applying controlled sound waves in microfluidic systems, the particles are entrained toward equilibrium points due to a radiation force induced by the ultrasonic waves at certain...

Our study aims to develop an analytical and numerical model to quantify the influence of a building's façade geometry and all its components (windows, balconies, etc.) on scattered and reflected sound waves. We have therefore chosen to adapt a diffraction model originally used in underwater acoustics and elastodynamics for ultrasonic waves and to apply it to airborne acoustics for a frequency...

Ice removal and the prevention of ice buildup is a hot topic in industry and academia due to its implications, e.g. on sensors, aircrafts and wind turbines. We recently researched de-icing and anti-icing methods using Surface Acoustic Waves (SAW) to transfer energy into the ice or water to melt it or protect it from freezing respectively. It has been shown that SAWs are a very energy efficient...

Composites, specifically fibre-reinforced polymers, are increasingly utilised in aerospace industry particularly as they are lightweight, and possess respectable mechanical properties capable of sustaining environmental constraints. Automated Fibre Placement (AFP) has emerged as a manufacturing solution in the composites industry over the past few years. It has improved the production process,...

Electrospray ionization (ESI) is the most widely used ionization technique in liquid chromatography-mass spectrometry (LC-MS), generating charged microdroplets that undergo evaporation and Coulomb fission to produce gas-phase ions. However, in high-flow ESI regimes, a significant fraction of large, highly charged droplets (up to 100μm) can enter the MS inlet. These droplets contribute to...

Mehdi Abdu Mohammed (Le Havre Normandy University)08/09/2026, 16:20A13 Physical Acoustics and Ultrasound
Internal erosion can produce localized losses of material inside fluid-saturated porous structures and detecting such hidden defects from outside the structure is difficult. This work studies, theoretically and experimentally, the transmission of normally-incident ultrasonic waves through a fluid saturated porous medium in which a thin solid layer is embedded at the midplane to stand in for...
