Thin-Film Metamaterials Called Sculptured Thin Films [PDF]

open access: yes, 2010
Morphology and performance are conjointed attributes of metamaterials, of which sculptured thin films (STFs) are examples. STFs are assemblies of nanowires that can be fabricated from many different materials, typically via physical vapor deposition onto rotating substrates.
