Three dimensional acoustic scattering from an M multilayered domain via an integral equation approach

An integral equation approach is derived for three dimensional acoustic scattering from an M multilayered domain. The integral equation is solved using the collocation method. To validate the method, we compare the exact and approximate results. The numerous matrix vector multiplications of our method may be thought a disadvantage. This problem can be overcome by using fast multiple methods where these operations are done very quickly.
