Elser and V. A. Podolskiy<br/>We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics—parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of...<br/>[Phys. Rev. Lett. 100, 066402] Published Mon Feb 11, 2008 Phys. Rev. Lett. 100, 066402 Justin Elser Viktor A.
