The finite-difference time-domain (FDTD) method is used to calculate the detailed specific absorption rate (SAR) within the human body. SAR distributions are calculated using incident frequencies of 100 and 350 MHz for three different cases: 1) a homogeneous man model in free space, 2) an inhomogeneous man model in free space, and 3) an inhomogeneous man model standing on a ground plane. These various cases are used to evaluate the advantage of inhomogeneous models over homogeneous models, and grounded models versus free space models. Finally, comparison is made between the results obtained here and those obtained experimentally or with the method of moments (MoM).
