Parallel Computation of Ultrasonic Wave Propagation in Orthotropic Composite Materials

There has been much effort devoted to modeling wave propagation and scattering in isotropic materials [1]. Most of these efforts have employed finite difference techniques to compute the time evolution of the wave field in materials with scatterers. The forward problem is important in improving and understanding ultrasonic testing methods. It is also important for solving the inverse problem of determining the material and flaw properties from the scattering data [2]
