Abstract
The particular anisotropy of a specific propagation surface orientation on a single crystal lithium tantalate substrate member is utilized to achieve low diffraction, low spurious response surface acoustic wave (SAW) propagation. The preferred embodiment utilizes a propagation surface that substantially coincides with a plane defined by the Euler angles Lambda = 0.degree., Gamma = 166.65 (+0, -0.3).degree., and Theta = 90.degree..
