摘要：

A secluded supersonic SAW is known to exist in an isolated direction on the (001) surface of certain cubic crystals. This wave consists of two evanescent partial wave components and is not polarized in a symmetry plane. Calculations are reported on this mode, using germanium as an example, and it is found that this wave continues to exist for some surface orientations different from (001). A one dimensional family of nonsymmetrical supersonic SAW geometries is identified and it is found to be joined to the family of supersonic SAW polarized in the (1 $($) over bar$$ 10) symmetry plane.
