| Abstract: | In this paper,the sine and cosine transforms are applied to transform 3 dimension FDTD to 2 dimension FDTD in layered media. We employ the transmitting boundary condition to eliminate reflections from the boundary of the domain,and use the superabsorption technique to improve the accuracy of FDTD.The method is applied to the ground probing radar with satisfactory results. |
