Boundary perturbation methods for high-frequency acoustic scattering: Shallow periodic gratings
Journal of the Acoustical Society of America
Despite significant recent advances in numerical methodologies for simulating rough-surface acoustic scattering, their applicability has been constrained by the limitations of state-of-the-art computational resources. This has been particularly true in high-frequency applications where the sheer size of the full-wave simulations render them impractical, and engineering processes must therefore rely on asymptotic models ͓e.g., Kirchhoff approximation ͑KA͔͒. However, the demands for highdoi:10.1121/1.2897104 pmid:18529172 fatcat:gxotrfg7rjaodpzs5pfmrpz5cy
