The aim of this research project is to develop calibratable measuring methods for contactless and non-destructive material characterization in the microwave and millimeter wave range. Based on transmission measurement methods, methods should be developed that enable the determination of all complex scattering parameters of a two-port based on reflection measurements. Passive reflectors are used instead of the receiving antenna. Another focus of this research project is the development of calibration methods for free space measuring systems. The focus here is on reducing the number of calibration standards, so that the mechanical displacements of antennas or calibration standards that are usually required can be dispensed with.
