The dispersion theory for reflectivity of s- and p-polarized light is considered. The problem of phase retrieval from reflectance of p-polarized light, in the presence of complex zeros of the reflectivity in the upper half of complex frequency plane, is addressed. In such a case the traditional Kramers-Kronig relations are not valid, but the maximum-entropy method will provide the required solution.
