Abstract : A new way to carry out numerical cellular telephone simulation in the presence of the head is presented. Here, two finite-difference time-domain FDTD simulations with different spatial and time resolutions are sequentially combined to perform a dual-grid FDTD DG-FDTD simulation. The DG-FDTD approach has the significant advantages to remain stable along the computation and to be easy to implement in a typical FDTD code. When compared with classical FDTD analysis, the DG-FDTD approach exhibits a reduction in computation time and memory requirements by a factor of 2.3 and 3.2, respectively, while providing accurate results both in near-field and far-field radiation.
