Acoustic waves have had widespread applications in fields as diverse as         medicine and nondestructive evaluation of materials.  Availability of           extremely short pulses would be an attractive improvement for these             uses.  Standard microelectronics fabrication techniques of deposition           photolithograph and etching may permit construction of acoustic sources         on a planar structure.  The laboratories available at Case Western              Reserve University permit experimental construction of such structures.         This research is both theoretical and experimental, with modeling and           calculations predicting performance of the experimental planar                  piezoelectric transducers and arrays of such transducers.  If                   successful, this research can provide design rules for creation of              acoustic arrays of value for high resolution metrology.
