The direction dependence of surface wave speed and the influence of electrically and
magnetically short/open circuit are investigated in this paper. First, the elastic, piezoelectric and
piezomagnetic coefficients in the considered ordinate systemare obtained byBonde transformation
from those in the crystal axis ordinate system. Then, the secular equation of surface wave is derived
fromthe free traction condition on the surface of half space with consideration of short/open circuit
case. Some numerical examples are given. The direction dependence of surface wave speed and
the influences of short/open circuit are shown graphically and discussed based on the numerical
results.
