Paper Abstract

The reflection of s- or p-polarized electromagnetic plane waves from an N-layer system of inhomogeneous ultrathin dielectric films in the vicinity of the classical Brewster angle is investigated analytically in the long-wavelength limit. The second-order approximate formulas for principal and polarizing angles are derived and their accuracy is estimated by using exact numerical methods for calculating the reflection characteristics of inhomogeneous films. It is shown that expressions obtained for characteristic reflection angles are of immediate interest to the solution of the inverse problem for nanoscopic-layered structures. A few novel straightforward methods for optical diagnostics of ultrathin layers are established.
