Abstract :
The influence of a conductive liquid on the characteristics of shear-horizontal acoustic waves of zeroth order (SH/sub 0/ mode) propagating in thin piezoelectric plates of lithium tantalate, lithium niobate, and potassium niobate was investigated. Experimental results obtained for SH/sub 0/ mode devices fabricated on lithium niobate plates are found to be in good agreement with theory. The data presented in this paper is useful for a proper design of various acoustic wave sensors operating in contact with conductive liquids.
