The heterogeneity has been considered both in rigidity and density. The study reveals that under assumed conditions, a torsional surface wave propagates in the medium. The velocities of torsional surface waves have been obtained. It is also observed that for a layer over a homogeneous half-space, the velocity of torsional surface waves coincides with that of Love waves. An attempt is also made to assess the possible propagation of torsional surface waves in a half-space with polynomial variation in rigidity and density, lacking a superficial layer.
