摘要：

A software package that provides an interactive and graphical environment for surface-acoustic-wave (SAW) and platemode propagation studies in arbitrarily oriented anisotropic and piezoelectric multilayers is described. The software, which runs on an IBM PC with math coprocessor, is based on our transfer-matrix formulation for calculating the characteristics of SAW propagation in multilayers, originally written for our mainframe computer. The menudriven software will calculate wave velocities and field variable variations with depth for any desired propagation direction; the graphics capability provides a simultaneous display of slowness or velocity and of SAW Δ v/v coupling constant curves, and their corresponding field profiles in either polar or cartesian coordinates, for propagation in a selected plane or as a function of one of the Euler angles. The program generates a numerical data file containing the calculated velocities and field profile data. Examples illustrating the usefulness of the software in the study of various SAW and plate structures are described. © 1990 IEEE
