Basic Concepts and Formalism

  • Afshin Moradi
Part of the Springer Series in Optical Sciences book series (SSOS, volume 230)


The book aims to present a systemic and self-contained guide to the canonical electromagnetic and electrostatic boundary-value problems in metallic nanostructures. In this way, the conduction electrons of a metallic medium are modeled as a degenerate electron gas, whose dynamics may be described by means of the hydrodynamic theory. Therefore, at first we need to know something about the hydrodynamic model of an electron gas. Then, we need to know something about the basic concepts and formalism of electromagnetic and electrostatic theories of an electron gas that will be used later in the book. For brevity, in many sections of this chapter the \(\exp (-i\omega t)\) time factor is suppressed. Furthermore, all media under consideration are nonmagnetic and attention is only confined to the linear phenomena.
