Abstract: The interaction of a λ/4 monopole antenna handset with a heterogeneous electromagnetic block human model is simulated by using finite-difference timedomain (FDTD) method. The human model is a cube of 0.655 cm, and the specific absorption rate(SAR) of the model in 7 different conditions is calculated at frequency 700 MHz. Several importantconclusions and proposal are given after analysing the calculated results and comparing them with the Hygienic Standard for Electromagnetic Radiation of China and USA.
