Assesment of SAR in a Simplified Body Model due to Hertz Dipole Exposure
This paper presents the assessment of a specific absorption rate (SAR) featuring a simple, canonical body model and several approximations useful in a rapid estimation of some quantities of interest in in high frequency (HF) dosimetry. The human body is modelled as a parallelepiped illuminated by a plane wave representing the field radiated by Hertz dipole in the far zone. Only component of the electric field tangential to the Hertz dipole is considered as an incident field component. The transmission coefficient approximation stemming from the modified image theory (MIT) is used for computation of the electric field at the air-body interface. The whole body average SAR is calculated for several frequencies, antenna lengths and antenna-body distances. The computational examples depict the behavior of SAR which is of particular interest for the transition frequency of 6 GHz.
