Abstract
Focusing of surface acoustic waves (SAW) due to elastic anisotropy of substrate crystals is investigated theoretically. For propagation on the (001) plane of GaAs, we find strong focusing effects of the SAW along certain directions. We also find that the number of independent pure-mode axes lying in the focusing directions is just one on the (001) surface.Keywords
