This paper presents an application of the bilateral dual-grid finite-difference time-domain (DG-FDTD) method. We propose to determine in a short computation time the specific absorption rate in the fetal brain of a pregnant woman at 900 MHz. The principle of the new technique consists in splitting the overall simulation into three FDTD simulations sequentially executed with an appropriate mesh. Results obtained with this approach are compared to the original FDTD and DG-FDTD methods.
