Abstract :
Ultrasonic modeling results are presented on backscattering of broadband pulsed Scholte waves and grazing underwater acoustic waves from a trench at a liquid/solid interface. The backscattered waves are characterized by interference of diffracted waves reflected from the trench bottom and the trailing steep side. The effects of trench width and depth are demonstrated.<>
