Notions of electromagnetic compatibility: wave propagation has long remained a privileged domain of radio-electricians; however, the current generalization of telecommunications, as well as that of digital systems for control and command, leads to taking into consideration the ambient "electromagnetic pollution", with the aim of controlling our environment. These electromagnetic disturbance phenomena are today of considerable importance, with the development of distributed computing, microelectronics, and finally power electronics characterized by strong currents and high frequencies. The purpose of the course is to raise awareness of EMC problems, to present the main sources of disturbances, to understand the modes of coupling, to specify the main remedies, as well as the evolution of standards. This EMC teaching is a discovery of the principles and causes, an outline of the possibilities of solution; it allows the listener to synthesize the physical knowledge acquired elsewhere, and thus to acquire a first qualification in a particularly current discipline. EMF also includes human exposure to electromagnetic fields or waves. The following points will be covered: concepts of short-term and long-term effects, regulatory context, quantification of phenomena induced in the human body (concept of induced current at low frequencies and Specific Absorption Rate at high frequencies), parameters determining the amplitude of phenomena (distance, frequency, voltage, current, … conductivities and permittivities of human tissues), Dosimetry (analytical and numerical methods).
