Reflection of surface acoustic waves on anisotropic media

摘要

Reflection of Rayleigh surface waves by shallow grooves or metallic strips on general anisotropic crystals is analyzed. In this paper, the groove or strip is considered as a small discontinuity which acts as a surface excitation source for the scattering of the incident wave. The problem is solved by using Fourier transform technique and integration in the complex plane. Reflection coefficients of the various geometries on quartz and lithium niobate are calculated in good agreement with experiment.
