title: Nonambiguous determination of optical constants for absorbing materials.
abstract: A recently proposed method for determining the optical constants of absorbing materials starting from reflectance measurements is analytically treated. The conditions for a nonambiguous determination of the optical constants are established. The values of the parameters satisfying these conditions are explicitly evaluated.
