    • Deformable wire array: fiber drawn tunable metamaterials 

      Fleming, Simon; Stefani, Alessio; Tang, Xiaoli; Argyros, Alexander; Kemsley, Daniel; Cordi, James; Lwin, Richard
      Published 2017
      By fiber drawing we fabricate a wire array metamaterial, the structure of which can be actively modified. The plasma frequency can be tuned by 50% by compressing the metamaterial; recovers when released and the process can ...
