Backscattering of Scholte waves and near-grazing underwateracoustic waves by a trench at a liquid/solid interface

摘要

Ultrasonic modeling results are presented on backscattering ofnbroadband pulsed Scholte waves and grazing underwater acoustic wavesnfrom a trench at a liquid/solid interface. The backscattered waves arencharacterized by interference of diffracted waves reflected from thentrench bottom and the trailing steep side. The effects of trench widthnand depth are demonstrated
