Mark Riffe" ], "comment": "66 pages, 20 figures, 40 exercises", "categories": [ "physics.class-ph" ], "abstract": "The interaction of electromagnetic fields with a solid is characterized by several interconnected response functions: the dielectric function $\\varepsilon(\\omega)$, index of refraction $N(\\omega)$, conductivity $\\sigma(\\omega)$, and optical impedance $Z(\\omega)$. Here we utilize three canonical models of dielectric response -- the damped harmonic oscillator, Debye polarization response, and the Drude model -- to discuss these four optical response functions. Special emphasis is devoted to the response of a Drude metal. Our main focus is on electromagnetic wave propagation through a material. We also discuss the relaxation of charge fluctuations within the context of the three canonical models of response.", "revisions": [ { "version": "v1", "updated": "2018-06-13T17:35:19.000Z" } ], "analyses": { "keywords": [ "canonical models", "dielectric response", "electromagnetic wave propagation", "debye polarization response", "drude model" ], "note": { "typesetting": "TeX", "pages": 66, "language": "en", "license": "arXiv", "status": "editable" } } }
