TRANSIENT REFLECTIONS OF SOUND FROM MULTILAYERED FLUID-SOLID MEDIA,

Abstract

The theory of the transient pressure field produced by the reflection of sound waves from multilayered fluid-solid media is developed. The sound originates at a line or point impulsive source in a two-dimensional semi-infinite fluid. An expression for the transient reflected pressure field is derived in terms of a double Fourier inversion integral over all the frequencies and horizontal components of all the wave numbers. The specific forms of the integrand within the inversion integral are presented for various types of pulses. (Author)
