Researches on the distribution law of vector sound field in elastic wedge bottom

The method based on elastic parabolic equation method for calculating the sound vector field has been studied.The vector field in water and corresponding seismic wave field had been calculated for infra-sound in oceanic environment with elastic wedge bottom.The effects on sound field distribution for different frequency and depth of sound source had been researched,result shows that there is sound energy leakage into the bottom,the position where leakage occurred can be determined by the ratio of the ocean ...
