title: Anisotropy of the acoustic plate modes in ST-quartz and 128°Y-LiNbO(3).
abstract: Orientation dependences of the phase velocity vn, coupling coefficient Kn(2), and power flow angle Ψ(n) for zero-order and high-order acoustic modes are calculated numerically in ST-quartz and 128°Y-LiNbO(3) plates with normalized thickness h/λ = 0.1, 0.25, 0.5, 1.0, 1.25, 1.5, and 1.67 (n is the mode order, θ is the angle between propagation direction and the x-axis, h is the thickness, and λ is the wavelength). Results of the calculations are experimentally verified using 128°YLiNbO(3) plates with h/λ = 1.0, 1.67 and θ = 0°, 30°, 60°, 90° as examples.
