Borshchan V.S., Rezvov Yu.G., Sivkova O.D. «Manufacture of a converter for surface acoustic waves» Приборы и техника эксперимента, 36, № 2, с. 189-190 (1993)

A converter for excitation of surface acoustic waves in piezoelectric materials is known, for manufacturing which they make a recess on a sound guide’s surface by the method of ion etching. A method for the mechanical fabrication of such a recess is described. By this method, a converter with a central frequency of 10.4 MHz at an excitation effectiveness of 27 db is made from lithium niobate Y+128-section.
