Mechanisms of subdiffraction free-space imaging using a transmission-line metamaterial superlens: An experimental verification

Ashwin K. Iyer and George V. Eleftheriades
This work presents experimental verification of free-space subdiffraction imaging using a Veselago-Pendry superlens [Sov. Phys. Usp. 10, 509 (1968); Phys. Rev. Lett. 85, 3966 (2000)] based on the negative-refractive-index transmission-line approach. The superlens is able to resolve two sources lambd ... [Appl. Phys. Lett. 92, 131105 (2008)] published Mon Mar 31, 2008.
