Strategy for the Fast Solving of Surface Acoustic Waves Velocity

Strategy for the Fast Solving of Surface Acoustic Waves Velocity

The solving of phase velocity is the groundwork and starting point for investigating the propagation properties of surface acoustic waves (SAW) and optimal cuts. The iterative numerical computation is needed in the calculation and the calculation capacities are very heavy. So it is important to impr...

description The solving of phase velocity is the groundwork and starting point for investigating the propagation properties of surface acoustic waves (SAW) and optimal cuts. The iterative numerical computation is needed in the calculation and the calculation capacities are very heavy. So it is important to improve the calculation velocity for every cuts. To the questions including solving velocity, precision and reliability, which the traditional method of surface effective permittivity and boundary condition determinant have, the mix method was put forward in this paper. Helped with material symmetry, continuity and suitable search step and interval, this method realizes solving of SAW velocity fast and accurately, which can provide some guide for the fast solving of SAW questions and cuts optimizing.
