The authors analyze electromagnetic modes in multilayered nanocomposites and demonstrate that
the response of a majority of realistic layered structures is strongly affected by the nonlocal effects
originating from strong field oscillations across the system, and is not described by conventional
effective-medium theories. They develop the analytical description of the relevant phenomena and
confirm their results with numerical solutions of Maxwell equations. Finally, the authors use the
developed formalism to demonstrate that multilayered plasmonic nanostructures support high-index
volume modes, confined to deep subwavelength areas, opening a wide class of applications in
nanoscale light management. 2007 American Institute of Physics. DOI: 10.1063/1.2737935
Nanolayered composites have been recently proposed to
serve as negative index systems, super- and hyperlenses,
photonic funnels, and other nanophotonic structures.111
The
typical thickness of an individual layer in these "artificial"
meta materials is of the order of 10 nm. Since this size is
