Description: The pressure amplitude distribution along the interface between a wedge-shaped fluid layer overlying fast and slow fluid bottoms were investigated using compute models based on the method of images. The pressure amplitude along the bottom rapidly falls off for distances closer to the apex than that at which adiabatic-mode theory predicts cut-off for the lowest mode. This distance is termed the dump distance for an acoustically fast-bottom condition. In the case of a slow bottom, because the speed of sound ratio is greater than 1, the dump distance does not exist. To facilitate scaling the acoustic fields, a scaling distance is introduced.
Notes: Title on documentation page reads: Acoustic pressure distribution on the bottom of wedge-shaped ocean.
