SUMMARY Acoustic field analysis results of surface acoustic wave dispersive delay lines using inclined chirp IDTs on a Y-Z LiNbO 3 sub-strate are described. The calculated results are compared with optical measurements. The angular spectrum of the plane wave method is applied to calculation of the acoustic fields considering the anisotropy of the SAW(More)
We present a simulation technique of ultrasonic fields and echo signals, that uses a digitized crosssection photograph of a test object and a digitized cross-section figure of an ultrasonic probe as input data. The input data file is referred to as a shape file. In the shape file, different colors are assigned to different materials, for example, red for a(More)
