Description
Hot Topic 4 of the EAA Summer School took place on 21–22 June 2025 at the Universidad de Málaga, ahead of Forum Acusticum / Euronoise. Noé Jiménez organised the course and taught it with Alicia Carrión and Alba Eroles Simó.
The first day covered wavefront shaping, focused beams and the angular spectrum method. Participants used MATLAB to back-propagate a target sound field, turn the resulting phase map into a lens geometry, and export an STL file for 3D printing.
The second day focused on biomedical ultrasound and experimental testing in water. The practical challenges used shaped beams to heat a target, rotate an object with an acoustic vortex, and move a floating particle along a trajectory.
