One and two dimensional devices electromagnetic simulation using parallelism on GPUs

Following the efforts performed in research and development of electromagnetic devices as antennas, optical fibers and microwaves devices we report a careful implementation of the Finite-Difference Time-Domain (FDTD) in a parallel environment. We use Graphic Processor Units (GPUs) to take advantage of FDTD parallel features and observe the time evolution of the electromagnetic fields in a Single Instruction, Multiple Data parallel implementation. It was observe performance gains up to 30 times when this parallel GPU solution are compared with a serial solution in a modern CPU.
