Abstract

A method for calculating the optical properties of amorphous metals is described. When the reflectivity at low photon energies is well represented by the Hagen-Rubens equation, the Kramers-Kronig relation can be expressed in terms of a ratio reflectance, and the optical phase so obtained has much greater accuracy than when obtained by the regular approach. As an example, the optical properties of amorphous Fe80B20 are derived.
