dispersion of love wave in a fiber-reinforced medium lying over a heterogeneous half-space with rectangular irregularity

This paper concerned with the dispersion of love wave in a fiberreinforced medium lying over a heterogeneous half-space. the heterogeneity is caused by the consideration of quadratic variation in density and directional rigidity of lower half-space. the irregularity has been considered in the form of rectangle at the interface of the fiberreinforced layer and heterogeneous half-space. the dispersion equation of love wave has been deduced for existing geometry of the problem under suitable boundary conditions using variable separation method. it has also been observed that for a homogeneous layer with rigidity lying over a regular homogeneous isotropic half-space, the velocity equation coincides with the classical results of love wave. the effect of the medium characteristics on the dispersion of love waves has been discussed and the results are displayed with graphs by means of matlab programming to clear the physical significance. the study of love wave dispersion with irregular interface helps civil engineers in building construction, analysis of earthquake in mountain roots, continental margins, and so on. it is also beneficial for the study of seismic waves generated by artificial explosions.
