The University of Ulm and the Faculty of Electrical Engineering, Computer Science and Psychology are striving to strategically strengthen the research field of micro- and mm-wave technology with the appointment of Prof. Damm. At the same time, research activities are to be expanded to include higher frequencies in the Terahertz (THz) range. In particular, the area of electromagnetic sensor technology for ​​biomedical applications and its interdisciplinary research are to be created in cooperation with the medical and biological faculties. The terahertz range is particularly interesting for this research, as the high frequencies enable much higher sensitivities. As a result, much smaller changes on the cellular level and much smaller concentrations of pathogens can be recorded using electromagnetic measurement technologies. Further, electromagnetic sensor technology opens up new possibilities for experimental biomedical research and future cost-effective point-of-care applications. The THz range also shows many molecule-specific spectroscopic resonances, which can be used to increase the sensitivity or to increase the selectivity with the direct identification of specific biomolecules by their spectroscopic finger print. Furthermore, the area of ​​high bit-rate data communication for mm and THz frequencies is to be strengthened by new measurement capabilities. The very successful research focus on radar technology by Prof. Waldschmidt at the Institute for Microwave Technology is to be expanded through new measurement technology up to the THz range for future ultra-broadband, high-resolution multi-channel radar systems for imaging. For this purpose, a THz measuring station is to be set up for measurements in the time and frequency range from approx. 325 GHz up to 6 THz. Initial equipment from the university and the Institute for Microwave Technology are available for this purpose. The measuring station combines vector measurement technology up to 750 GHz with photonic signal generation and detection up to 6 THz. For each of the targeted research projects, several of the different measurement techniques are always required at the same time, which is why a dedicated measurement station must be set up.

乌尔姆大学和电气工程、计算机科学和心理学学院正在努力战略性地加强达姆教授的任命，加强微波和毫米波技术的研究领域，同时扩大研究活动。特别是，将与医学和生物学院合作创建用于生物医学应用的电磁传感器技术及其跨学科研究领域。这项研究特别感兴趣，因为高频可以实现更高的灵敏度，因此，使用电磁测量技术可以记录更小的细胞水平变化和更小的病原体浓度。此外，电磁传感器技术开辟了新的领域。太赫兹范围还显示出许多分子特异性光谱共振，可用于提高灵敏度或通过直接识别特定分子来提高选择性。此外，Waldschmidt 教授在雷达技术方面的新测量能力也将加强毫米波和太赫兹频率的高比特率数据通信领域。微波技术研究所将通过新的测量技术扩展到太赫兹范围，用于未来超宽带、高分辨率多通道成像雷达系统。为此，将建立一个太赫兹测量站，用于测量。时间和大学和微波技术研究所的初始设备可用于此目的，频率范围为约 325 GHz 至 6 THz。测量站将高达 750 GHz 的矢量测量技术与高达 6 THz 的光子信号生成和检测相结合。对于每个目标研究项目，总是需要同时使用几种不同的测量技术，这就是为什么必须建立专门的测量站。
