Fig. 2

Transmission and absorption lines (a, b) and their transmission phase (left y axis) and delay time (right y axis) (c, d) of the system with polarization angle θ = 0° (a, c) and 90° (b, d), respectively. In (a) and (b), the dashed lines show the resonant position at the other polarization. The fitting parameters of the theoretically analyzed lines in (a) and (b) are (in THz) 6.71, 110.07, 2.25, 0.46, and 0.74, and 5.73, 4.13, 72.83, 0.33, and 0.27 for κi, Q1i/sqrt(ε0m1i), Q2i/sqrt(ε0m2i), γ1i, and γ2i, respectively. Spatial distributions of the electric field for the cases with UGGs (e (blue line), f, j) and LGNRs (e (red line), g, k) only along the z axis (e) and in the corresponding graphene planes (f, g, j, k). Spatial distributions of the electric field (left panels) and the corresponding z component (right panels) of the symmetric mode (SM) (h, @5.747 μm; l, @5.511 μm) and antisymmetric mode (AM) (i, @4.917 μm; m, @4.636 μm) at polarization angles θ = 0° (h, i) and 90° (l, m), respectively. The upper inserts in e show z component of the electric field for the case with d = 50 nm, while the lower insert depicts the position of the field in the main plot. Signs “+” and “−” donate the resonating surface charges; the darker color refers to a larger charge density
