Abstract
Foot currents induced in human bodies exposed to 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 simulations, it is shown that the foot currents obtained by using inhomogeneous models have slightly lower values than those obtained by using homogeneous models. From simulation results and measurement data, it is found that the theory of FDTD method makes a good agreement with the experiment. It is also found that the maximum foot currents of 20.73 and 18.51 mA were obtained by measurements and calculations, respectively, when a human stands barefoot at a distance of 10 m from the cellular phone base station. From measurements and calculations, the foot currents are reduced by a factor of about 0.72–0.91 and 0.78–0.8, respectively, when the condition is changed from standing barefoot to wearing shoes. © 2008 Wiley Periodicals, Inc.
