Study on the validity of the formalism of norton to describe the propagation of electromagnetic waves on the surface of the body

In this paper, we focus on the study of electromagnetic waves that allow the communication between two antennas located on the surface of the human body. The link between the antennas leads to the appearance of space wave, whose level increases with height above the skin, and a surface wave which, on the contrary, decreases with the altitude. We use the wave propagation model of Norton with the notion of Somerfield’s attenuation. We give the limits of validity of this formalism in the area containing mainly surface waves. To generate this type of waves, the excitation sources used are small elementary electric dipoles with normal polarization.
