Abstract
Scattering of a plane SAW by a circular, perfectly conducting disk on a piezoelectric halfspace is considered. A new theoretical approach allows to take into account the electric anisotropy of the substrate and gives the solution for the electric charge density on the disk in a form of fast convergent series for a wide range of wavelength of the SAW.References
