Abstract
The main objective of this proposed article is to provide explanations to justify the validity of the results of the studies of the interaction between the electromagnetic fields and the human body. It can also find direct applications in the characterization and modeling of the macroscopic electrical properties of the biological media for assessing the effects of fields induced by electromagnetic radiation sources in the human body to set up new standards on the Human exposure to electromagnetic fields. To do this, we have taken into account the different physical phenomena of propagation of a hyper-frequency electromagnetic plane wave and on the other hand, the experimental values in order to model the electrical behavior of human biological tissues based on an equivalent electronic circuit model composed of capacities, resistance and reel, which assimilates the biological tissues of the skin, grease, blood. This model using the characteristic impedance of the dielectric support makes it possible to evaluate the voltage induced by the electromagnetic waves of the hyper-frequencies in the studied biological system. The results of the simulations obtained from computer tools demonstrate that the hyper-frequency electromagnetic waves can result in an elevation of the electrical potential of the biological tissues. Despite this potential is a decreasing function of the penetration depth.

Summary
The potential risks for people exposed to interactions between electromagnetic fields and the human body are real and require protective measures [3]. Exposure to these sources may be voluntary in the case of medical diagnosis such as an NMR imager, hyperemia therapy, ablatherapy or involuntary mobile telephony, radio or television transmitters, household appliances, computer screens, televisions, security systems in shops and airports, high voltage lines, transformers, etc. The health effects generated are mainly a function of the coupling mechanism, the nature of the fields and the duration of exposure [6] These phenomena are all the more important as the intensity and/or the frequency of the signal are high [3] [7]. To avoid all forms of electromagnetic compatibility [9] [10] [11]
