Electromagnetic field intensity distributions for TE polarization. (a) |Ey|2 in the y = 0 plane (xz plane), (b) |Ey|2 in the graphene plane, (c) |Hx|2 in the y = 0 plane and (d) |Hz|2 in the y = 0 plane. In panel (b), the region enclosed by the white dashed line is the graphene square array. In panels (a), (c) and (d), the regions denoted by white dashed lines are the silicon square array and the two-dimensional multilayer grating, while the black dashed lines indicate the graphene square array owing to its ultrathin nature. |
