ABSTRACT

In this chapter the physics of the interaction between metallic

systems (bulk, surfaces and nanoparticles) and the electromagnetic

radiation will be considered. The light-matter interaction will be

analyzed for a plane-wave incident field as well as for a dipolar

radiation, which represents the electromagnetic field emitted by

molecules. We will start discussing the Maxwell’s equations, the

dielectric function of metals and the localized surface plasmon

resonances of metallic nanospheres. Then the Green’s function

formalism and the electromagnetic scattering theory will be

introduced. Finally the radiative and non-radiative decay rates of

emitting molecules near metal surfaces and nanoparticles will be

discussed.
