Abstract
It has been shown (1) that the reflection of an absorbing medium covered with a convenient transparent film gives interference fringes irregularly spaced because of the specific phase shift at the reflection on the absorbing material. Two equations allow the determination of n and k (n = n - jk is the complex refractive index corresponding to a monochromatic wave E = Eoejwt), if we know the fringes position and the corresponding reflection power at the minima and maxima.
