Simulations of acoustic fields on the surface of semi-infinite piezoelectric crystal,excited by finite-length IDT including surface acoustic waves and bulk waves,are made using numerical tools. With inverse Fourier transform of displacement components in the frequency domain,the distribution of acoustic wave pulse amplitude over time can be obtained. By analyzing the acoustic wave modes in three displac-ement components on the surface,some information can be found. It should be explained that… CONTINUE READING
