Dissertation im Bereich Physical & Computational Acoustics (PCA)

RECENDT develops optical and acoustic technologies for non-destructive characterization of materials in terms of chemical and physical/structural properties and for process-integrated testing and inline analysis. The acquired data is processed with cutting-edge data analysis methods and provided to the process-owners as usable and valuable information. With an interdisciplinary team and state-of-the-art photonic technologies, RECENDT thus covers the entire field of intelligent sensor technology.

To actively strengthen our team, we are looking for a

PhD student (m/f/d)

Linz, Austria / 30 hours per week

You will study guided waves in piezoelectric plates and layers within the framework of an FWF standalone project.

Piezoelectric materials convert mechanical deformation into electrical signals and vice versa, making them essential for many sensing and communication technologies. Guided waves propagating in such materials are strongly influenced by the coupling between mechanical and electrical fields as well as by the electrical boundary conditions at the surface. Understanding these effects is important for both material characterization and the development of novel acoustic devices.

In this role, you will investigate guided wave propagation in piezoelectric plates and layered structures using laser-ultrasonic experiments and numerical modelling. The work aims to improve the characterization of piezoelectric materials and explore new possibilities for controlling wave propagation through tunable electrical boundary conditions.

Your tasks:

• Investigation of guided wave propagation in piezoelectric plates and layers
• Laser-ultrasonic measurements and data analysis
• Numerical modelling and simulation of wave propagation
• Presentation of results at scientific conferences and publication of research findings

You will become part of a global community of experts, present your work at academic conferences, and publish scientific papers, thereby further developing your ability to conduct independent research.
