WKB Across Caustics: The Screened-WKB Method
Oscar P. Bruno, Martin D. Maas
We present a new methodology, based on the WKB approximation and Fast Fourier Transforms, for the evaluation of wave propagation through inhomogeneous media. This method can accura…
Vector potential-based MHD solver for non-periodic flows using Fourier continuation expansions
Mauro Fontana, Pablo D. Mininni, Oscar P. Bruno +1
A high-order method to evolve in time electromagnetic and velocity fields in conducting fluids with non-periodic boundaries is presented. The method has a small overhead compared w…
A Windowed Green Function method for elastic scattering problems on a half-space
Oscar P. Bruno, Tao Yin
This paper presents a windowed Green function (WGF) method for the numerical solution of problems of elastic scattering by "locally-rough surfaces" (i.e., local perturbations of a…
Fourier continuation method for incompressible fluids with boundaries
M. Fontana, Oscar P. Bruno, Pablo D. Mininni +1
We present a Fourier Continuation-based parallel pseudospectral method for incompressible fluids in cuboid non-periodic domains. The method produces dispersionless and dissipationl…
Regularized integral equation methods for elastic scattering problems in three dimensions
Oscar P. Bruno, Tao Yin
This paper presents novel methodologies for the numerical simulation of scattering of elastic waves by both closed and open surfaces in three-dimensional space. The proposed approa…
