Abstract

The surface wave, which first appeared more than a century ago as a “nonphysical” solution of Maxwell’s equations, is considered today as a kind of “panacea” for bridging the nano and macroworlds in nanophotonics and, especially, plasmonics. Despite the advances made in the understanding of surface waves and their widespread use in various elements and systems of modern optoelectronics, an ever-increasing number of investigators from various branches of science are showing interest in “surface-captured light.” This is mostly due to the discovered potential control of the localization and direction of propagation of electromagnetic excitations at the nanoscale, which creates new opportunities for local photoconversions in chemistry, subwave cartography, chemical and biological sensors, spatial movement, and directed heat transfer at the nanolevel, active photonic elements with new information carriers, etc. (Brongersma and Kik 2007).
