RadioFrequency electromagnetic (EM) waves constitute nowadays common and ubiquitous elements of our surrounding and living environment. They are not only employed in military applications, but also increasingly used in our daily life for various exploitations: wireless communications, radars for automotive, home automation and now the tremendous market of connected objects. Their impact on the human health remains however a large question mark with controversial investigations results performed at different levels, microscopic and macroscopic ones, as well as at the population level with epidemiologic studies. Within this context, this presentation aims at highlighting the reasons for such a controversy, recalling different interaction mechanisms, which may occur between EM waves and the living, and also presenting near-field RF exposure systems developed at LAAS-CNRS in collaboration with different partners.
