Abstract

The influence of radio-frequency (RF) field orientation on specific absorption rate (SAR) in a human body is investigated in this paper. Three basic field orientations have been simulated: electric field vector, magnetic field vector and Poynting vector parallel to the longitudinal axis of a human body. The influence has been investigated in frequency range from 10 MHz to 2450 MHz with assistance of CST Microwave Studio program environment. Here the homogeneous ellipsoid, as a human body model, is irradiated by plane wave, representing far-field zone of antenna.
