Figure 2. Transmission spectrum of the structures of figure 1 with the primary design which is comprised of two resonance mode using the Drude model: (a) resonator of filter 1 with the radius of r = 200 nm- peak transmission (0.67, 0.81), (b) resonator of filter 2 with the diagonal of D = 510 nm or x-coordinate of vertical edge in 180 nm peak transmission (0.17), (c) resonator of filter 3 with the radius of r = 200 nm- peak (0.52, 0.56), (d) resonator of filter 4 with the radius of r = 230 nm or x-coordinate of vertical edge in 200 nm- peak (0.61, 0.68).
