Theory of light transmission through periodically structured nano-apertures

Abstract

As illustrated throughout this book, surface plasmons (SPs) are well known for their capabilities of concentrating light in subwavelength volumes and also for guiding light along the surface of a metal. But this does not exhaust the phenomena related to SPs. Even the scientific community working on this subject was greatly surprised in 1998 by the suggestion that SPs could enhance the transmission of light through subwavelength holes. That seminal paper reported that, when subwavelength holes are disposed on a metallic film forming a two-dimensional (2D) array, the transmission of light through this structure is greatly enhanced at some particular wavelengths. © 2007 Springer.
