Abstract (in Japanese) (See Japanese page) 
(in English) Spoof surface plasmons (SSPs) can be controlled by subwavelength structured metallic surfaces, and regarded as a concept to extend the conventional (optical) surface plasmons to low frequencies. Recently, it has been shown that the SSPs can guide a thin metallic film with subwavelength fine structures. This structure has a feature that dispersion curves of the SSP are insensitive to the depth of the film, and therefore many potential applications will be expected. On the other hand, when such thin structures are analyzed with the conventional finite-difference time-domain (FDTD) method, the maximum stable time step has to be reduced to ensure its numerical stability. This will lead to unwanted increase of total time steps. In order to avoid this problem, we use the recently proposed semi-implicit FDTD scheme [K. Fujita, IEICE Trans. Electron., Vol.J97-C, No.11, pp.429-440, 2014] based on the Newmark-Beta method. The effectiveness of the semi-implicit FDTD scheme is shown in the analysis of the SSPs excited in the thin metallic film.
