“…It is convenient to use Fresnel approach for analytical solution, as well as for numerical solution, as already emphasized. Those solution are compared to rigorous numerical approach described in [22] and obtained using Numerical Electromagnetic Code (NEC) software. The second goal of this work is comparison between 𝑆𝐴𝑅 𝑊𝐵 induced in parallelepiped and cylindrical human body model.…”

“…The assumption of current distribution is the simplest way to determine the current distribution along vertical dipole antenna. Our previous work showed that numerical model with assumed current distribution (sinusoidal or triangular) gives satisfactory results for electrically small antennas [22] by decreasing the computational cost without appreciable loss of accuracy. The results of numerical approach with assumed current distribution are compared to rigorous numerical approach obtained from NEC.…”

The paper deals with an efficient procedure to study human exposure to vertical dipole antenna above a flat lossy half space. The closed form expressions for the corresponding irradiated electrical field are obtained assuming the sinusoidal and triangular current distribution along the antenna, respectively. The corresponding integral field expressions are evaluated by means of numerical integration and analytical procedures. The computations have been undertaken in the far field zone for various antenna parameters and compared to rigorous numerical model. Provided the field radiated from the vertical dipole is determined, whole body average Specific Absorption Rate (SARWB) is computed in a simple parallelepiped model of the human body and cylindrical model of the human body, respectively. Index terms-Human exposure, vertical dipole, radiated field, Specific Absorption Rate (SAR), parallelepiped model of the human body, cylindrical model of the human body.
