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. It is also found that the maximum foot currents of 20.73 and 18.51 milliamps were obtained by measurements and calculations when a human stands barefoot at a distance of 10 meters from the cellular phone base station, respectively. From measurements and calculations, the foot currents are reduced by a factor of about 0.72~0.91 and 0.8 when the condition is changed from standing barefoot to wearing shoes, respectively.
