## Abstract An analytic formulation is proposed to obtain both complex permittivity and thickness of a single‐layer material from reflection ellipsometry data obtained at more than two angles of incidence. The principle consists in decoupling the equations that involve both thickness and complex pe

Abstract
Several experimental results on common single‐layer samples have been obtained in the microwave domain using the reflection ellipsometry technique and two different data analysis procedures. They lead to estimations of complex permittivity as a function of the angle of incidence, frequency, and thickness. The influence of measurement uncertainties is discussed. © 2003 Wiley Periodicals, Inc.

## Abstract For in situ measurement of the complex permittivity of planar materials, a free‐space system based on reflection or transmission ellipsometry has been developed and extended to microwave frequencies. Different angles of incidence were studied in the range [35–50°]. Original numerical me
