Acoustic Scattering for Complex Shapes by Using the DWBA
Description
Uses the Distorted Wave Born Approximation (DWBA) to compute the
acoustic backward scattering, the geometry of the object is formed by a
volumetric mesh, composed of tetrahedrons. This computation is done efficiently
through an analytical 3D integration that allows for a solution which is
expressed in terms of elementary functions for each tetrahedron.
It is important to note that this method is only valid for objects whose
acoustic properties, such as density and sound speed, do not vary significantly
compared to the surrounding medium. (See Lavia, Cascallares and Gonzalez, J. D. (2023).
