Abstract :
In this paper, an FDTD-based numerical simulation method developed to study the acoustic propagation processes in piezoelectric superlattices is briefly introduced. Comparing with the traditional ¿-function model method, the FDTD-based method is more fundamental and is more convenient to be extended to higher dimensional cases, while the ¿-function model method can be only used in the one-dimensional situation. To improve the simulation efficiency, the CUDA technique has been applied in our calculation and a significant speedup has been observed.
