A new hybrid method of moments (MoM)/finite-difference timsdomain (FDTD), with a sub-gridded finite-difference timedomain (SGFDTD) approach is presented. The method overcomes the drawbacks of homogeneous MOM and FDTD simulations, and so permits accurate analysis of realistic applications. As a demonstration, it is applied to the short-range interaction between an inhomogeneous human body and a small UHF WID antenna tag, operating at, 900MHz. Near-field and far-field performance for the antenna are assessed for different placements over the body. The cumulativt. distribution function of the radiation efficiency and the absorbed power are presented and analyzed. The algorithm has a fivefold speed advantage over fine-gridded FDTD.
