High-Density Array of Stacked Split-Ring Resonators Derived from Block Copolymer Self-Assembly with Epsilon-Near-Zero |
| 초록 |
We fabricated a high-density array of “pagoda-like” nanorods over a large area (~ cm2) to realize silver stacked split-ring resonators (SSRRs). This array was prepared by confining lamellar-forming polystyrene-block-poly (methyl methacrylate) copolymer (PS-b-PMMA) in cylindrical nanopores of anodized aluminum oxide (AAO) template treated by neutral brush, followed by O2 reactive ion etching and tilted silver deposition. This complex nanostructure array showed optical polarization difference and nearly zero permittivity at visible wavelength regions. This array could be applied to realize large-sized metamaterials working at visible and NIR wavelengths. |
