It includes theoretical considerations and measurement results of four different materials. Overall, a maximum measurement uncertainty of 0.0153 for the relative permittivity and 0.001 for the loss tangent in the W-band can be achieved. Depending on the variation of the material's thickness, the implemented setup changes lead to an reduction of the measurement uncertainty of 8 to 58 %.||Conference:||48th European Microwave Conference, EuMC 2018||URI:||http://hdl.handle.net/11420/6514||ISBN:||978-287487051-4||Type:||InProceedings (Aufsatz / Paper einer Konferenz etc.)|
