METHOD FOR GENERATING MECHANICAL WAVES BY CREATING AN INTERFACIAL ACOUSTIC RADIATION FORCE

摘要

The present invention relates to a method for generating mechanical waves in a viscous-elastic medium (11), that comprises the step of generating an acoustic radiation force (15) in the viscous-elastic medium (11) by the application of acoustic waves focused on an interface (13) separating two areas (11, 14) having different acoustic properties.
