(a) and (b) Schematic of a conventional fishnet structure with 5 metallic layers. (c) Real part of the effective index for 2-layer, 3-layer, 4-layer, and 5-layer fishnet structures retrieved from the simulated scattering parameters. (d) Sketch of corresponding simplified multilayer system. (e) Real part of the retrieved effective index for simplified multilayer systems contains 2 layers, 3 layers, 4 layers, 7 layers, 9 layers, 11 layers, and 14 layers B medium.
