Abstract :
The permittivity of wire medium presents not only anisotropy, but also frequency and spatially dispersion. In this paper, a parallel spatially dispersive finite-difference timedomain (FDTD) method based on the graphics processing unit (GPU) is designed and implemented. The proposed method is validated by numerical results of sub-wavelength imaging. High acceleration ratio demonstrates the efficiency of the parallel dispersive FDTD algorithm.
