Assessment of Absorbed Power Density (Sab) at the Surface of Flat Lossy Medium in GHz Frequency Range : A case of Hertz dipole

The paper deals with an analytical assessment of the absorbed power density (S
_ab
) due to radiation of Hertz dipole above a lossy half-space representing the human tissue. The effect of two media interface is taken into account via the corresponding reflection/transmission coefficients arising from the Modified Image Theory (MIT). The frequency range of fifth generation (5G) mobile communication systems is of interest. Some illustrative scenarios are presented.
