The problem of reflection of Love waves at a rigid barrier is studied in this paper by taking the barriers of different sizes. The barrier is present in the homogeneous, isotropic and slightly dissipative surface layer. The reflected waves are obtained by Wiener – Hopf technique and Fourier transformations. Numerical computation has been done and conclusion has been drawn from the graphs of amplitudes versus wave number of the reflected Love waves. The amplitude of the reflected waves decreases rapidly with the increase in wave number and then it decreases at slower rate and ultimately becomes saturated which shows that love waves take a long time to dissipate and go on moving around earth surface for a long time. The comparison of graphs also shows that the barriers of large sizes result in reflected Love waves with larger amplitudes.
