The research tasks include the development and construction of a compact THz ellipsometer device, based on the time-domain principle. The development project will be pursued in a cooperation with the company SENTECH Instruments GmbH. The goal is an ellipsometer demonstrator which is suited for the quantitative analysis of soil, sand and regolith samples. In order to do this, the polarization-dependent optical response of suitable reference samples in the infrared and THz spectral range shall be measured in ATR geometry. The optical response shall be evaluated in optical models with the intention to derive information about the composition and particle size in the samples.

• successfully completed scientific university studies (Master's degree, diploma or equivalent) in physics or a related subject area
• fundamental knowledge in applied Optics
• hands on experience with femtosecond lasers and/or ellipsometry
• capability to work in an interdisciplinary, international team is desired
• first practical experiences in programming with Python or LabVIEW are desirable
• good knowledge of German and/or English required; willingness to acquire the respective missing language skills
