Plasmon (SubWavelength) Waveguides
A surface plasmon-polariton wave (SPP) is a guided surface wave along the interface of a metal film or a metal substrate and a surrounding dielectric material. This type of wave is formed by the coupling of an electromagnetic wave to oscillating free electrons at the surface of a conductor. The first pioneering investigation on this phenomenon was carried by Ritchie in the 1950s . Subsequently, for the next half a century, the studies of SPPs and their applications have expanded from the diagnostics of metal surface qualities to a broad spectrum of scientific endeavors in physics, chemistry, and biology [2–10]. Furthermore, the subwavelength model size and very slow group velocity over an unusually large bandwidth of the SPP wave may provide exciting applications to the field of nanophotonics and microfabrication [4, 6, 10].
