Metal Optics Near The Plasma Frequency

The second half of this book sets out several more sophisticated treatments of the response of a single metal surface to electromagnetic radiation. The relations between general forms of the response functions and additional boundary conditions are discussed for a variety of phenomenological models, the HD, the specular reflection model, the "dielectric approximation", the "semi-classical infinite barrier" model and several others. Also, microscopic surface response calculations based on a quantum mechanical model containing a surface potential for the electrons are presented and their relationships to the HD and the SCIB model are illustrated. Finally, we deal with two surface response functions d±(m) and dll(m), which contain the integrated effect of spatial dispersion and surface properties on measurable quantities such as reflection coefficient or surface plasmon dispersion. Their relation to measurements as well as to microscopic or phenomenological response calculations is discussed."--Pages v-vi
