Abstract

Recent advances in nano-fabrication have enabled a host of nano-photonic experiments involving subwavelength metallic structures. This flurry of activity has, in turn, reawakened interest in surface plasmon polaritons (SPPs) and inspired theoretical research in this area. Although the fundamental properties of SPPs have been known for nearly five decades, there remain certain subtle issues that could benefit from further critical analysis. Here, numerical simulations are used to verify the detailed structure of long-range SPPs.
