This paper deals with a numerical FDTD approach to solve a particular ground-penetrating problem. Classical Yee FDTD formulation is used to simulate layered media on a perfectly electrically conductive plate (PEC). It is shown that an alternative of the step 3-D PML formulated by Sullivan is well adaptated to surround the computational domain. In particular, the PEC can be easily extended to the PML medium without any extra reflection error.
