Abstract Limitations of a microwave free-space method based on two-polarized forward scattering are discussed. The method can be used e.g. to measure the average volume of the inclusions of a granular material in the Rayleigh-region. The minimum and the maximum thicknesses of the measured material are determined by the complex permittivity, the shape and the number density of the inclusions of the material, the measurement frequency and the properties of the measurement equipment. Theoretical background of the method is presented. The measurable thickness range of several common granular materials with typical properties, calculated on the basis of the theory have been tabulated.
