Negative refraction and imaging using plasmonic slabs and layers
2006 International Symposium on Biophotonics, Nanophotonics and Metamaterials2006pp. 406–406
Abstract
Summary form only given. Double-negative medium, with permittivity and permeability simultaneously negative, exhibits a negative value of the refractive index and the resulting negative refraction has been demonstrated. One interesting property of a double-negative medium is that a thin flat slab can serve as a superlens, but realizing double-negative media in optical frequencies is rather difficult that there is a strong urge to find substitutes that are easier to realize and more robust to operate.
