معرفی
Samuel Raetz is an Associate Professor at Le Mans University, affiliated with the Institute of Acoustics - Graduate School and the Laboratoire d'Acoustique de l'Université du Mans (LAUM). He leads the LAUM's Opto-Acoustics & Laser Ultrasonics research operation, focusing on advanced acoustic techniques for material characterization and non-destructive testing applications.
Dr. Raetz's research spans several key areas in acoustics and materials science, with particular emphasis on laser ultrasonics, opto-acoustics, and time-domain Brillouin scattering. His work explores picosecond acoustics in materials under high pressures, non-contact non-destructive testing of composite materials, and the study of guided elastic waves including zero-group-velocity Lamb modes. His research has significant applications in material science, structural health monitoring, and high-pressure physics. He has developed innovative methodologies for 3D and 4D imaging of materials under extreme conditions, with applications ranging from aerospace engineering to biological materials characterization.
His recent publications demonstrate a strong focus on advanced imaging techniques and the phononic properties of both natural and engineered materials. He has made significant contributions to understanding wave propagation in complex structures, from water ice under high pressure to biological materials like mantis shrimp exoskeletons and abalone shells. His work bridges theoretical modeling with experimental validation, often developing novel methodologies that push the boundaries of acoustic characterization.
Dr. Raetz is actively involved in academic education, having contributed to the development of the international master on Wave Physics & Acoustics at Le Mans University. He has also been instrumental in creating open-access interactive online courseware in acoustics through the Acoustics Knowledge Alliance (ASKNOW) project, demonstrating his commitment to innovative educational approaches in the field.
