Love wave frequency in an orthotropic crust over a double-layered anisotropic mantle

In the present paper, investigation has been made to study the propagation character of Love wave in an orthotropic substratum being layered doubly over anisotropic porous mantle. Separate expressions for displacement components have been derived for each of the three layer and suitable boundary conditions have been imposed to derive the dispersion equation of the wave in a closed form in terms of Whittaker function. It has been found that inhomogeneity parameter associated with the rigidity and the density of the layered medium has a special bearing on the Love wave propagation. Orthotropic properties and initial stresses of the media also affects the velocity of the wave to a great extent has been shown graphically.
