Lectures
Physical principles of acoustic wave propagation: Wave equation. Acoustic quantities: displacement, velocity, pressure, phase velocity, acoustic impedance, energy and intensity. Acoustic wave modes: bulk waves, Rayleigh waves and Lamb waves. Reflection, refraction and transmission. Absorption and attenuation. Diffraction, near field and far field. Non-linear effects. Acoustic streaming. Cavitation. Sonoluminescence. Piezoelectricity and piezoelectric materials. Biological effects of ultrasound.
Instrumentation: Transducers. Sensors. Acoustic properties of materials. Waveguides and resonators. Acoustic lenses and mirrors.
Applications of ultrasound: Diagnostics/imaging. Doppler. Material testing and industrial applications. High power applications. Sonar. Acoustic microscopy. Micro-cleaning and grinding. Drilling. MEMS. Laser ultrasound. Chemical applications. Agglomeration and particle manipulation.
Lab
The lab is performed in groups of two students, and is presented by a written report.
Project
A project is chosen within an elective but by the coordinator accepted subject. The project is presented as a written report and also as a 20-min oral presentation for the other students. The other students are supposed to provide opposition to the oral presentation.
