Precise measurement of weak magnetic fields is an area that plays a key role not only in geophysics and metrology, but also in medical diagnostics and space research. The habilitation lecture will focus on the principles of operation of modern, precise vector magnetometers for low magnetic fields - orthogonal fluxgate and a quantum, superconducting SQUID. It will present their applications in geomagnetic field measurement and metrology, and their limitations given by the principle of operation. The presentation will include approaches to reducing and determining low-frequency noise in a real environment, where the results achieved in the research group represent the state of the art in the field. The lecturer will also present the results of cooperation with academic partners and examples of practical applications of precision magnetometers.
Michal Janošek, Ph.D. works as an assistant professor at the Department of Measurement at the Faculty of Electrical Engineering of the Czech Technical University in Prague. He studied measurement and instrumentation technology at the Faculty of Electrical Engineering of the Czech Technical University, where he successfully defended his doctoral thesis in the field of measurement technology in 2014. During his doctoral studies, he completed research stays at the Technical University of Braunschweig, the Stellenbosch University, and the South African National Space Agency (SANSA), where he has been post-doctoral student and a visiting scientist repeatedly between 2018 and 2024. His research activities focus primarily on the precise measurement of very weak magnetic fields and their use in geophysics and medicine.
He has published over 20 articles on this topic in impact journals and is co-author of two European patents. In the field of education, he teaches courses in Modern Sensors, Advanced Sensors, and Analog Signal Processing and Digitization, both in Czech and English.
He has contributed to the creation of a university textbook and in recent years has been working as a supervisor and specialist supervisor for doctoral students. Students repeatedly praise his teaching with excellent ratings in faculty surveys.
Dr. Janošek's habilitation thesis, entitled Precise Magnetometers for Geophysics and Metrology, was very positively evaluated by all three reviewers - Prof. Marina Diaz Michelena (INTA, Spain), Dr. Werner Magnes (Austrian Academy of Sciences, Institute for Space Research) and RNDr. Zdeněk Arnold, CSc. (Institute of Physics, Czech Academy of Sciences). The reviewers particularly praised the high professional level of the thesis, the author's extensive publishing activities, his involvement in international cooperation, and the direct impact of his research on practical applications in industry.
