Application of the perfectly matched layer (PML) absorbing boundary condition to elastic wave propagation
(Journal of the Acoustical Society of America, 1996-11)
A method is presented for application of the perfectly matched layer (PML) absorbing boundary condition (ABC) to the P?SV velocity–stress finite?difference method. The PML consists of a nonphysical material, containing ...
An investigation of the small slope approximation for scattering from rough surfaces: Part I: Theory
(Journal of the Acoustical Society of America, 1995-04)
The small slope approximation (SSA) of Voronovich [Sov. Phys. JETP 62, 65–70 (1985)] is a promising method for application to scattering from many natural surfaces. The theory gives a systematic expansion that can be ...
