Abstract: Electromagnetic properties of materials can be determined through the measurement of s-parameters and the use of well-developed algorithms. For broad-band and accurate material characterization, transmission line methods are very attractive. While sample preparation can be challenging in coaxial and waveguide, planar transmission lines are well-suited to address this limitation. The positioning of the sample is crucial for obtaining accurate results in these techniques. We have applied a reference plane invariant technique, previously demonstrated only in coaxial and waveguide transmission lines, to a coplanar waveguide line for the first time, to the best of our knowledge. This approach eliminates the need for precise measurement of the sample’s position along the line. Flexibility and repeatability of the method has been shown using experimental and simulation results.
