Abstract
Problems of measurement appear when characterizing heterogeneous materials at microwave frequencies in transmission lines or waveguides, even when these materials are known to be homogenizable. A model for a perturbed line is introduced. The measurement cell containing the sample is represented by an unperturbed line in series with resonators which model the coupling between the sample and the measurement cell. Finally, the intrinsic characteristics of the material are computed from the unperturbed line.<>
