An investigation of the small slope approximation for scattering from rough surfaces: Part II: Numerical studies
(Journal of the Acoustical Society of America, 1997-05)
The small slope approximation (SSA) of Voronovich [Sov. Phys. JETP 62, 65–70 (1985)] is a promising method for modeling wave scattering from rough surfaces. The SSA T-matrix series, which can be interpreted as an expansion ...
Acoustic scattering from a fluid-elastic solid interface using the small slope approximation
(Journal of the Acoustical Society of America, 1994-09)
In this paper the small slope approximation is applied to acoustic scattering from a randomly rough fluid–elastic?solid interface. Expressions for the zeroth?, first?, and second?order bistatic scattering cross sections ...
Implementation of transparent sources embedded in acoustic finite-difference time-domain grids
(Journal of the Acoustical Society of America, 1998-01)
The finite-difference time-domain (FDTD) method is a simple but powerful numerical method which has been used to perform a wide variety of complex simulations. One of the considerations in using this method is modeling the ...
