Optical Properties of Iron to 30 eV

Abstract

A modified approach closely related to the Drude, Lorentz-Drude and Bren-del-Bormann theories is developed to fit the experimental data of the optical properties of metals. This work, while simplifying and redefining the parameters of previous models, can be directly compared with the parameters of the Brendel-Bormann model. As a test of validity, our model is compared with the Brendel-Bormann model and experimental data for gold. Our model shows excellent agreement with the experimental data for gold (up to 5 eV) and iron (up to 30 eV).
