An efficient multigrid calculation of the far field map for Helmholtz and Schrödinger equations (English)
0 references
The authors propose a new efficient calculation method for the far field map associated with scattering problems governed by the Helmholtz and Schrödinger equations. This is simply based on a reformulation of the corresponding integral over a complex contour, for which the system under study is efficiently solved by an iterative method.
