Physical Ultrasonics
The University of Mississippi

The primary thrust of the Physical Ultrasonics Research Group is the physics of ultrasonically mediated phenomena.  This includes the study of the ultrasonic properties of soft tissue, fabrication and characterization of phononic metamaterials, study of micellar fluid phase transitions, signal propagation in heterogeneous, dispersive and viscoelastic media, development of tissue-mimicking phantoms and the physics of acoustic cavitation.
