1. Acoustic and elastic propagation in wave guide and complex media

Guided waves propagation in fluids and solids are ubiquitous in many areas of physics and in engineered mechanical systems. This session aims to bring together researchers to discuss new advances in the theoretical analysis, the computational modeling and the measurement of acoustic and/or elastic waves in waveguide structures. Topics of interest could include liquid-filled elastic pipes, interaction of guided waves with defects, and duct acoustics.

2. Acoustic and elastic wave scattering

Acoustic and elastic wave scattering is a common physical phenomenon occurring when  sound wave arrives at a boundary with discontinue surface impedance. Since scattered acoustic/elastic wave carries some inherent information of obstacles or defects, it is widely used in ultrasound imaging, target recognition and nondestructive testing, but it is also of importance in theoretical developments describing accurately the scattering by complex structures (single or aggregates of finite complex-shaped scatterers, multilayered heterostructures, interfaces, etc.). The field covers a large variety of scales from several meters down to hundreds of nanometers. Studies on theoretical models, approximation methods, numerical simulations and fine experiments of acoustic and elastic wave scattering are expected in this section.
