Abstract(in Japanese) (See Japanese page)
Abstract(in English) We have extended the contour-path effective-permittivity technique to three-dimensional (3-D) problems, in which a reasonably accurate solution can be obtained for arbitrarily-shaped dielectric media. In this article, we newly extend the dispersive contour-path (DCP) technique to 3-D problems to obtain an accurate solution for arbitrarily-shaped dispersive media. The DCP algorithm is introduced into the FDTD method based on the trapezoidal recursive convolution technique, in which the position of the dispersive medium is considered in each cell for 3-D problems. We investigate a metal sphere and evaluate the scattering cross section. The results from the present technique are compared with the Mie solutions and those from the conventional staircase FDTD method to confirm the effectiveness of the 3-D DCP technique.
