The near and far-field transmission characteristics of nanoscale annular array metamaterials fabricated using ion beam lithography are investigated both computationally and experimentally. Experimental results in the far-field regime demonstrate high transmission efficiencies in the near infra-red region of the electromagnetic spectrum for these devices, in excellent qualitative agreement with a previously developed numerical model. The diffractive near-field behavior of such structures is discussed, with a particular emphasis on the implications associated with verifying such predictions experimentally.
