Optical interaction with nanostructures is studied by the field of plasmonics. Recently, the potential of subwavelength confinement and enhancement of optical fields close to appro‐ priately designed nanoscale objects has opened a gateway to extensive investigations into plasmonic optical phenomena. The purpose of this book is to provide a detailed introduc‐ tion to the basic modeling approaches and an overview of enabled innovative phenomena. Surface waves open a gateway to a wide spectrum of physical phenomena providing a fer‐ tile ground for a number of applications. Discovery of metamaterials with tunable electric and magnetic features has allowed for a rich phenomenon, i.e. expansion of the wide spec‐ trum of structures capable of supporting surface waves. Surface plasmon polaritons (SPPs) are electromagnetic excitations occurring at the interface between a conductor and a dielec‐ tric. These are evanescently confined in the perpendicular direction. It is possible to imitate the properties of confined SPPs by using geometrically induced SPPs, called spoof SPPs. The proposed phenomenon may take place at lower frequencies. It might be concluded that the surface structure could open a gateway to spoof surface plasmons. The former serves as a perfect prototype for structured surfaces. The main research agenda of this book is aimed at the study of the modeling techniques and novel functionalities such as plasmonic enhance‐

The topics addressed in this book cover the major strands: theory, modeling and design, ap‐ plications in practical devices, fabrication, characterization, and measurement. It is worth‐ while mentioning that the strategic objectives of developing new artificial functional
