Models of Electromagnetic Response of Materials
Keyword(s):
Physical models that relate the generalized complex permittivity and complex conductivity to the electronic structure of matter are introduced. The classical models of Drude and Lorentz give expressions for the complex index of refraction in a dielectric, while Drude models a metal as a plasma. Reflection and transmission properties of interfaces are expressed in terms of the complex index of refraction. Special consideration is given to the behavior of light propagation in the frequency vicinity of an atomic resonance of the material. Finally, measurement techniques are presented that are applicable to the determination of the parameters of a Lorentz/Drude representation of electromagnetic transmission in matter.
