Abstract :
Full contour maps of basic propagation characteristics of pseudo-surface acoustic waves on LiTaO3 are calculated and plotted. Orientations, in which temperature stable pseudo-surface acoustic waves exist, were found. In particular, this is a range of Euler angles Φ = 30°, θ = 30°-40 °, Ψ = 116°-125°.
