Pec (1967) used the ray theory to derive the frequency equation of Love-waves propagating in a vertically inhomogeneous, isotropic medium. Bhattacharya (1970) studied the propagation of Love-waves in an inhomogeneous, isotropic layer over a homogeneous half-space. The shear-wave velocity and the modulus of rigidity in the layer were assumed to vary linearly along the direction of propagation and it was shown that the phase velocity of love-waves decreases or increases according to their direction of propagation along the increasing or decrealing shear-wave velocity and the rigidity of the layer. Negi and Singh (1973) extended the investigations of Bhattacharya by considering the inhomogeneities of exponential type in lateral and vertical directions. The variations of velouity and rigidity were assumed to be of the typ
