Diffraction Integrals for Piezoelectric Surface Waves: Construction and Discussion thereof.
Abstract
Diffraction integrals for the elastic-electric waves that propagate along the piezoelectric surface are constructed from elementary solutions of the wave equations. These integrals involve depth-dependent angular spectra which are calculable from aperture functions in the usual way. Upon setting the depth coordinate equal to zero, they go over into specialized versions that have been put forward elsewhere. The usefulness of these integrals relative to surface acoustic wave devices depends upon how well aperture functions can be approximated, and upon the adequacy of considering only the wave components at the surface. At present, there is no clear answer to either question.
