In order to simulate acoustic scattering of irregular object, the target need to be gridded.
The absorption coefficient which is frequency-dependent is considered, and it is applied to calculating broadband acoustic scattering model of underwater complex object.

Hence, this study suggests DtN2 to be the primary absorbing boundary condition to be employed when solving high-frequency acoustic scattering
problems by elongated scatterers.
Among the topics are a boundary element solution of thermal creeping flow in a nanometer single mixer, evaluating interface cracks, rotational symmetry applied to boundary element computation for nuclear fusion plasma, fundamental solutions for inverse obstacle acoustic scattering
, the volume integral equation method for analyzing scattered waves in an elastic half space, and analyzing layered soil problems with an alternative multi-region boundary element method technique and a new infinite boundary element formulation.
The mean energy initial rise is due to the dominant contribution of the acoustic scattering
mechanism until it reaches to a certain threshold value about 10, 100 and 2 kV/cm for InP, GaP and [Ga.
Arnold, a senior scientist at Lockheed Palo Alto (CA) Research Laboratory, wanted a software system that meets both the image and signal processing requirements of his acoustic scattering
