We study the problem of determining the electromagnetic properties of a stratified medium given only the amplitude of the reflected waves. Under some assumptions, the problem is formulated as the inverse scattering problem for a Schrödinger operator in impedance form. We show that a unique reconstruction from the modulus of the reflection coefficients is in general impossible and explain the cause of non-uniqueness. Several augmented sets of data allowing a unique reconstruction are suggested, and the corresponding numerical examples are provided.
