The problem of the reflection and refraction of elastic waves in the case of an isotropic medium has been discussed extensively (Cf. Ewing et. al. 1957, Brekhovskikh 1960). Transmision of elastic waves at oblique incidence through a straufied solid medium consisting of number of parallel plates of different materials and thickness was studied theoretically by Thomson (1950). He used the matrix calculus to systematize the analysis and to present the equation in a form suitable for compu’ation. Haskell (1953) used matrix method to study dispersion properties of Love and Rayleigh waves in an isotropic homogeneous medium. This technique is now known as Thomson-Haskell matrix method. The method has been used by several authors, e.g. Dorman (1962), Harkrider and Anderson (1962), Hannon (1964 a, b). Haskell (1960) applied this method to study the crustal reflection of plane SH waves. He derived an equation for the amplitude of the free surface displacement due to plane SH waves incident at any angle at the base of a layered crust. The same author (Haskell 1962) used this method for the crustal reffection of P- and svwaves. He derived expresions, in terms of layer matrices for the motion of the free surface when plane harmonic P- and SV- waves are incident at any given angle at the base of a horizontally layered crust. In these investigations Haskell has shown the variation of the surface amplitude with the angle of incidence and time period for a single crustal layer model.
