Summary
Introduction
The ability to localize electromagnetic energy below the diffraction limit of classical optics featured by surface plasmon polaritons (SPPs) (electromagnetic surface waves sustained at the interface between a conductor and a dielectric) is currently being exploited in numerous studies ranging from photonics, optoelectronics, and materials science to biological imaging and biomedicine [1]. While the basic physics of SPPs has been described in a number of seminal papers spanning the twentieth century [2, 3], the more recent emergence of powerful nanofabrication and characterization tools has catalyzed a vast interest in their study and exploitation. The dedicated field of plasmonics [4] brings together researchers and technologists from a variety of disciplines, with the common aim to take advantage of the subwavelength light confinement associated with the excitation of SPPs.
Most interest is focused on the optical regime, where SPPs are strongly confined to the respective metal/dielectric interface, i.e. where subwavelength mode localization is achieved in the direction perpendicular to the interface. These strongly confined SPPs occur at frequencies which are still an appreciable fraction of the intrinsic plasma frequency of the metal in question. In this regime, the motion of the conduction electrons at the interface is dephased with respect to the driving electromagnetic fields, leading to a reduction in both phase and group velocities of the SPP, and, therefore, to strong localization. A considerable fraction of the SPP field energy resides inside the conductor.
