Abstract

Abstract: We present a new conformal finitedifference time-domain scheme for the electromagnetic scattering problem. It adopts the interpolation of the nearest electric components for the distort field and the deform area, which provides a more accurat value of the contour-path. We illustrate the application of the algorithm proposed here on scattering problem with several examples. Results show that the agreement between the conformal FDTD and the theory or the measured data is excellent even if the timestep by our method is longer than that by the conventional FDTD.

Key words: FDTD, conform scheme, electromagnetic scattering
