The results of an effort to fabricate elastic wave transducers for use on the end of garnet fibers is reported herein. Essential properties for the materials under consideration, namely, fibers and piezoelectric transducers, are included as background together with exposition pertaining to the various types of modes which may be propagated as elastic waves along cylindrical fibers. The transducer design approach considered is described. Observations are noted for the gadolinium gallium garnet fibers supplied via NRL from another contractor. The fibers supplied represent a new crystal growth technology which exhibit various kinds of defects which prevented their use. This report documents the various problems encountered. Author
