Plasmonics is fast becoming a dominant technology for the 21st century. The classic text of H. Raether appeared in 1988, but the potential of surface plasmon remained inactive for a decade. It is now recognized that surface plasmon, which may be present on smooth, or corrugated particulate metal surfaces, has enormous potential in the field of optical computing, new optical devices and more recently in biological and medical research. These emerging applications are the result of the unique properties of the surface plasmons, which are confined on a two-dimensional surface and can have dimensions considerably smaller than the optical wavelengths. Surface plasmon may be, to a reasonable extent, controlled in two dimensions, by trapping and transporting optical energy in nano-scale structures. At first glance this possibility seems similar to the optical wavelengths. However, typical optical wave-guides, in contrast to plasmonic devices, must be three-dimensional and have wavelength characteristics.
In addition, the two-dimensional nature of plasmonic structures makes them compatible with modern lithographic methods used for the preparation of integrated circuits. The potential of plasmonics in chemical and biological research is now being realized. An early application is surface-enhanced Ramon scattering (SERS), the mechanism of which is still a subject of research. Another known application of plasmonics is surface plasmon resonance (SPR), which is used to study biomolecule binding reactions. SERS and SPR depend on the two ends of metal structures, random particles and a smooth surface. Modern nanofabrication technologies facilitate the application and understanding of plasmonics, allowing the preparation of numerous metallic nanostructures, in particular regular patterns of particles, holes or other characteristics. These metallic nanostructures are already known to exhibit unusual and unexpected optical properties such as anomalously larger optical transmission through nanowires of sub-wavelength and transmission-direction rather than diffraction of light. In addition, these are strong optical fields with sub-length length dimensions near such structures.
These fields provide opportunities for new experimental capabilities such as wavelength optical images. Plasmonics is a highly interdisciplinary science that depends on the efforts of physicists, chemists, and biologists. Many subdisciplines are involved, such as computational electrodynamics, nanofabrication, bottom-up chemical self-assembly and biochemical spectroscopy, to name a few. Consequently, and perhaps appropriately, the many new results using plasmonics are appearing diffusively in many magazines. Given the breadth and potential of plasmon technology, now is the time for a magazine dedicated to this important new science. We are therefore pleased to introduce Plasmonics, a peer-reviewed journal to serve as the focal point for the principles and applications of surface plasmon. The launch of Plasmonics is the culmination of two years of hard work by people around the world. The editorial board and regional editors represent global experts in the science of plasmony.
These scientists are recognized internationally in their respective plasmonic fields and clearly define the future direction and the high level of scientific integrity that will be applied to the manuscripts published in Plasmonics. Subsequently, we thank the editorial board and regional editors for their time, support and continued efforts. We especially thank these people for their enthusiasm for the creation of this magazine. The scope of plasmonics encompasses all aspects of the oscillation properties of the free electrons in the metals and the interactions of these plasmons with the surrounding environment. Topics include advances in the theory, physics and applications of surface plasmon to the emerging areas of nanotechnology, biophotonics, detection, biochemistry and medicine.
