Chew, Weng Cho Hesford, Andrew J. 2015-09-25T20:09:26Z 2015-09-25T20:09:26Z 10000-01-01 2007 2007 A parallel MLFMA is also developed for 3-D, penetrable, acoustic scatterers. This is paired with the distorted-Born iterative method (DBIM) for inverse scattering. DBIM requires repeated solutions of the forward problem to compute an image. With the linear complexity offered by the MLFMA forward solver, DBIM reconstructions proceed with greatly-reduced computation. This allows the solution of very large inverse-scattering problems.
