Sažetak
The paper deals with an analytical assessment of a whole-body averaged specific absorption rate (SAR_WB) when human body is illuminated by a short dipole antenna. The body is represented by a simple parallelepiped whose electric properties correspond to relative electric permittivity and electric conductivity of muscle tissue. The antenna-body distance and frequency are changed while the antenna parameters and body geometry are constant. In the computation of transmitted field into the body used for SAR_WB calculation, the air-body interface is taken into account by means of transmission coefficient stemming from Modified Image Theory (MIT). First, the theoretical background is outlined and then the results depicting the behaviour of SAR_WB with respect to antenna-body distance and frequency are presented. The resulting SAR_WB values do not exceed the basic restriction nor for occupational nor for general population.
