摘要：The Finite-Difference Time Domain (FDTD) method has become a standard simulation technique in computational electromagnetics. It has been extended and improved for accurately treating almost any kind of problem involving complex materials with arbitrary geometry and it continues to be an active field of research. The method has become so powerful that it is used as the computational core of not only many in-house tools but also commercial packages used to design electromagnetic systems (Reflexw, CST, EMPIRE, XFDTD, etc). Computational tools, such as FDTD, have become power-ful tools for GPR user, since the time-domain nature of FDTD-based programs enables the visualization of the causal evolution of complex electromagnetic phenomena such as the propagation of electromagnetic pulses in GPR scenarios that involve layered media, dispersive media, objects of arbitrary shape, etc. In the following paper several scenarios found during the GPR survey are simulated using FDTD and the results are commented on.
