Abstract:

Additions to and modification of a computer program for the numerical study of piezoelectric surface wave propagation are described. The main addition to the program is the calculation of surface wave attenuation using an expression based on a perturbation analysis and the viscosity tensor which accounts for losses due to the Akheiser mechanism. Other additions and modifications include the evaluation of stored energy expressions and changes in the format and normalization of the output data.
