• PROPAGATION OF RAYLEIGH WAVES DUE TO TWO OPPOSITELY PLACED PARALLEL RIGID BARRIERS IN THE LIQUID LAYER

Abstract

In this paper the problem of Rayleigh wave propagation due to two oppositely placed, parallel rigid plane barriers has been discussed. The plane vertical barriers of small depth H (x = 0, a) are erected artificially in the surface of the deep ocean. Deep ocean is a liquid half space given by . The elastic medium is homogeneous, isotropic and slightly dissipative. The reflected, transmitted and scattered waves have been obtained by Fourier transform and Wiener-Hopf technique. The numerical computations for the amplitude of the scattered waves have been made versus the wave number. As the wave number goes on increasing, the amplitude of the reflected waves falls rapidly.
