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 polyvinyl chloride samples with lengths 5, 10, and 20 mm. © 2014 Springer-Verlag Berlin Heidelberg.eninfo:eu-repo/semantics/closedAccessAlgorithmsOptimizationScattering parametersComplex permittivityComplex reflectionDielectric behaviorMeasurement of complex permittivityMeasurement proceduresNumerical proceduresOptimization algorithmsReflection measurementsDielectric materialsAlgorithmsOptimizationScattering parametersComplex permittivityComplex reflectionDielectric behaviorMeasurement of complex permittivityMeasurement proceduresNumerical proceduresOptimization algorithmsReflection measurementsDielectric materialsArticle11641701171010.1007/s00339-014-8303-92-s2.0-84906316974Q2WOS:000340583000022Q2
