                         reflection measurements. In the procedure, as a first step, a 
                         graphical method is applied to analyze on the complex 
                         reflection-coefficient plane the general pattern of dielectric 
                         behavior of the sample. Then, as a second step, optimization 
                         algorithms are utilized for retrieving electrical properties of 
                         samples. The procedure requires measurement of complex reflection 
                         scattering parameters of at least two samples with different 
                         lengths. It has been validated by X-band measurements of three
