Optical hyperspace for plasmons: Dyakonov states in metamaterials

Zubin Jacob and Evgenii E. Narimanov
We show that the subdiffraction imaging behavior observed in the magnifying superlens experiment, [Smolyaninov et al., Science 317, 1699 (2007)] is due to the hyperbolic dispersion of Dyakonov plasmons supported by the device. These states which are a special case of Dyakonov surface waves [Dyakonov ... [Appl. Phys. Lett. 93, 221109 (2008)] published Thu Dec 4, 2008.
