TS method combined with PMMA as a template was successfully used to create extraordinarily smooth metal nanostructures with a desirable feature size and morphology for plasmonics and metamaterials. The advantages of this method, including the high resolution, precipitous top-to-bottom profile with a high aspect ratio, and three-dimensional characteristics, make it a unique technology for the fabrication of integrated metallic structures, and is very suitable for the fabrication of plasmonic structures, especially for subwavelength field confinement. It is reasonable to anticipate that our methodology can be applied to a wide variety of plasmonic applications due to its easy fabrication and flexibility.
