Summary:
This letter presents the graphic processor unit (GPU) implementation of the finite-difference time-domain (FDTD) method for the solution of the two-dimensional electromagnetic fields inside dispersive media. An improved Z-transform-based finite-difference time-domain (ZTFDTD) method was presented for simulating the interaction of electromagnetic wave with unmagnetized plasma. By using the newly introduced Compute Unified Device Architecture (CUDA) technology, we illustrate the efficacy of GPU in accelerating the FDTD computations by achieving significant speedups with great ease and at no extra hardware cost. The effect of the GPU-CPU memory transfers on the speedup will be also studied.
