Research abstract
A PROGRAM IS PROPOSED TO INVESTIGATE ACOUSTIC AND MECHANICAL PROPERTIES OFF A CLASS OF MATERIALS FOR USE AS ACOUSTIC LENS DEVICES. THE MATERIALS, SYNTACTIC FOAMS, CAN BE COMPOSITIONALLY VARIED OVER WIDE RANGES TO AFFECT THE ACOUSTIC IMPEDENCE, SOUND VELOCITY, AND ATTENUATION. FUTHERMORE, THIS CLASS OF MATERIALS IS RELATIVELY INSENSITIVE TO ENVIRONMENTAL CHANGES, THUS KEEPING LENS ABERRATION TO A MINIMUM. THE OF THE PHASE I PROPOSAL IS TO GENERATE SUFFICIENT DATA TO PERMIT LATER FABRICATION OF A GRADED DENSITY LENS STRUCTURE BY CENTRIFUGAL CASTING.
