In order to take advantage of the significant benefits afforded by computational electromagnetic techniques, such as the finite-difference time-domain (FDTD) method, solvers capable of analyzing realistic problems in a reasonable time frame are required. Although software-based solvers are frequently used, they are often too slow to be of practical use. To(More)
Designing nanoscale devices presents a number of unique challenges. As device features shrink, the computational demands of the simulations necessary to accurately model them increase significantly. This is a result of not only the increasing level of detail in the device design itself, but also the need to use more accurate models. The approximations that(More)
No longer relegated to radio frequency (RF) engineers, antenna designers, and military applications, electromagnetic analysis has become a key factor in many areas of advanced technology. From 3 GHz PCs and wireless computer networks, to PDAs with Internet capabilities and the seemingly ubiquitous cell phone, it seems that electronic designs increasingly(More)
Although researchers have presented individual techniques to efficiently utilize the peripheral component interconnect (PCI) bus, their contributions fail to provide a direct path to large communication bandwidth for FPGA-based hardware accelerators. Because of the increasing use of FPGAs as application accelerators, there is a need for another, more(More)
