Clément is building an acoustic levitator and is also working on the modeling part of it.
If you want to make your own levitator, which can be a great educational tool, you can look at these resources:
- Tutorial with multiple references here: https://www.instructables.com/Acoustic-Levitator/
- and a journal by Asier Marzo, Adrian Barnes and Bruce W. Drinkwater entitled “TinyLev: A multi-emitter single-axis acoustic levitator” in Review of Scientific Instruments.
