Accurate modeling of pulse propagation and scattering is of great importance to the Navy. In a non-dispersive medium a fourth order in time and space 2-D finite difference time domain (FDTD) scheme representation of the linear wave equation can be used. However when the medium is dispersive one is required to take into account the frequency dependent attenuation and phase velocity. Using a theory...
Scientists at the Naval Research Laboratory (NRL) are engaged in a broad spectrum of research. In order to provide the high performance computing resources to support that work NRL has recently obtained a three cabinet XD1 with 432 Opteron 275 dual core CPUs, 144 Vertex II FPGAs, and 6 Virtex 4 FPGAs. This paper will examine the applicability of the XD1 to these scientific problems
