Abstract

Currents induced in human feet near a cellular phone base station were calculated by the finite-difference time-domain (FDTD) method and measured by a parallel plate meter at 1869 MHz. From simulation results and measurement data, it is found that the theory of FDTD method makes a good agreement with the experiment. Layer currents distributed in the human body are also obtained by the FDTD method. It is found that the highest layer currents distributed in the human body occur in the area of the chest. From the layer current profiles, it is also found that the maximum induced body current density is below the excitation threshold level of 1 mA/ cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The impact of clothes on the induced currents is also presented. It is found that there is only a little difference in the magnitude of current distributions between the human model with and without clothes.
