Description

The course aims to cover several aspects of human interaction with non-ionizing electromagnetic fields (EMF) including not only the undesired exposure from artificial sources but also the biomedical applications of electromagnetic fields. The course deals with basic aspects of electromagnetic fields in the environment, coupling mechanisms between humans and electromagnetic fields, established biological effects of electromagnetic fields from static to high-frequency range, international safety guidelines related to limiting human exposure to those fields, including relevant exposure limits and safety guidelines, electromagnetic-thermal dosimetry models and the related analytical/numerical solution methods.

Illustrative examples include analysis of power lines, transformer substations, PLC systems, RFID antennas, wireless power transfer (WPT) systems and radio base stations pertaining to 2G/3G/4G and 5G mobile communication systems.

This is followed by some examples of biomedical applications of electromagnetic fields, including transcranial magnetic stimulation (TMS), transcranial electrical stimulation (TES), and also some electrotherapy and magnetotherapy techniques. In addition, some illustrative computational examples pertaining to thermal modelling of certain ophthalmological procedures will be given.

Finally, the last part of the tutorial deals with the stochastic modelling of electromagnetic fields. As input parameters of models used in bioelectromagnetism and electromagnetic dosimetry suffer from inherent uncertainty they are treated as random variables.
