Abstract :
In this paper, we discuss the relation between the high transmissivities and these resonances in more detail. It is revealed that the high transmissivity based on the FPR is determined by the grating thickness, while the GMR and SPR by the periodicity. On the basis of these results, we design the polarizer which operates at a required wavelength by changing the periodicity. A high transmissivity of more than 85% is observed at each of the resonances.
