Description: An experimental acoustic levitator for high-temperature containerless processing has a round cylindrical levitation chamber and only one acoustic transducer. Stable levitation of a solid particle or liquid drop is achieved by exciting the sound in the chamber to a higher-order (non-planar) resonant mode that makes a potential well for the levitated particle or drop at some point within the chamber.
