Abstract : The aim of this series of two papers is to propose a new experimental tool based on the reflection ellipsometry technique for in situ characterization of single-layer dielectric materials at microwave frequencies. In the first part of this paper, the theoretical part of the technique and the associated multistep numerical algorithm used to estimate the complex permittivity of a sample have been presented. In this second part, we focus on the experimental setup and on the results. We report the estimated values of the complex permittivity for several types of materials and compare them with results obtained by the Fresnel method. We show that measured values agree with those currently published.
Keywords : Complex permittivity Fresnel coefficients ellipsometry free-space methods material characterization microwave frequencies polarization reflexion
