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.
