Abstract (in Japanese) (See Japanese page) 
(in English) A thin metal film sandwiched between dielectric gratings is analyzed using the finite-difference time-domain method. By a proper choice of the fill factor $f_{\rm H}$ (the ratio of the width of the high index material to the periodicity), the transmission wave can be selected to be either the TE or TM wave, or both. We first consider the case where the fill factor is taken to be unity; the dielectric gratings become homogeneous layers. Both of the TE and TM waves can be transmitted by the Fabry-P\'{e}rot resonance in the dielectric layers at a wavelength of 1.2 $\mu{\rm m}$. Next, we treat the structure for $f_{\rm H}$ = 0.5. The excitation of the surface plasmon, which is generated by the diffracted TM wave, transmits the incident wave through the thin metal film. As a result, an extinction ratio of more than 15 dB is obtained over a wavelength range of 1.5~$\mu{\rm m}$ to 1.75~$\mu{\rm m}$. Finally, we investigate the structure for $f_{\rm H}$ = 0.05. Only the TE wave is transmitted at a wavelength of 0.98 $\mu{\rm m}$, at which the resonance occurs in the dielectric gratings.
