Analysis of Planar Skin Model Exposed to Dipole Antenna Radiation Featuring the Use of the MoM-MoM Approach

Abstract

The paper deals with high frequency dosimetry analysis of a planar skin model exposed to a dipole antenna radiating in the GHz frequency range. The thin equivalent strip of a perfect electrically conducting (PEC) center-fed antenna is based on the electric field integral equation (EFIE) formulation in the frequency domain solved by means of method of moments (MoM), while the simple planar model for high frequency assessment is based on EFIE formulation for lossy homogeneous biological body solved by the same numerical approach. The electric field obtained using the EFIE-PEC part is subsequently utilized as the incident field in the EFIE-dielectric part of the proposed model. The numerical results for the surface antenna current, the equivalent surface current, and the induced electric field on the surface of the planar model are given, as well as a comparison of several field measures obtained at the averaging surface of planar models of varying thickness and width, respectively. The results could be found useful in the development of computational dosimetry models in the assessment of exposure of humans to electromagnetic fields in the GHz frequency range.
