Description: A contactless material-processing concept involves the levitation, heating, and cooling of a sample of material through the coordinated use of electromagnetic and acoustic fields. The electromagnetic field would be used for both levitation and heating, while the acoustic field would be turned on to levitate the sample whenever the electromagnetic field must be weakened below the minimum strength required for levitation.
