The paper presents a study on Love wave propagation in a anisotropic
visco-elastic layer overlying a rigid half space. The characteristic frequency
equation is obtained and the variation of the wave number with frequency
under the combined effect of visco-elasticity and anisotropy is analysed
in detail. The results show that the effect of visco-elasticity on the
wave is similar to that of anisotropy as long as the coefficient of anisotropy
is less than unity
