A finite-difference time-domain solution to scattering from a rough pressure-release surface
(Journal of the Acoustical Society of America, 1997-12)
The finite-difference time-domain (FDTD) method is a numerical technique that makes no explicit physical approximations to the underlying problem. The quality of a FDTD-based solution typically is determined by the ...
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 ...
