(a), (c), and (e) The real part of effective index for 1-, 2-, 3-, 4-, and 5-symmetric-functional-layer fishnet structures retrieved from the simulated scattering parameters with the different parameter: (a) df = 1.0 mm, = 4.3; (c) df = 0.5 mm, = 4.3; (e) df = 0.6 mm, = 8. (b) (d) and (f) real part of the effective index for 2-, 3-, 4-, and 5-layer conventional fishnet structures retrieved from the simulated scattering parameters with the different parameter: (b) hf = 2.0 mm, = 4.3; (d) hf = 1.0 mm, = 4.3; (f) hf = 1.2 mm, = 8.
