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通过任命Damm教授来战略性地加强微波和毫米波技术的研究领域。与此同时，研究活动将扩大到包括太赫兹（THz）范围内的更高频率。特别地，用于测量的电磁传感器技术领域 生物医学应用及其跨学科研究将与医学和生物学院合作创建。太赫兹范围对这项研究特别感兴趣，因为高频使灵敏度高得多。因此，使用电磁测量技术可以记录细胞水平上的小得多的变化和小得多的病原体浓度。此外，电磁传感器技术为实验生物医学研究和未来具有成本效益的即时护理应用开辟了新的可能性。THz范围还显示出许多分子特异性光谱共振，其可用于增加灵敏度或增加选择性，通过其光谱指纹直接识别特定生物分子。此外， 毫米和太赫兹频率的高比特率数据通信将通过新的测量能力得到加强。微波技术研究所的Waldschmidt教授在雷达技术方面非常成功的研究重点将通过新的测量技术扩展到THz范围，用于未来的超宽带，高分辨率多通道成像雷达系统。为此，将建立一个THz测量站，用于在时间和频率范围内进行测量，325 GHz至6 THz。大学和微波技术研究所为此提供了初步设备。该测量站将高达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一个专用的测量站。
