摘要：

The Maloney and Smith method used to account for sheets thinner than the cell size of the finite-difference time-domain (FDTD) method is extended to the case where both the sheet and the surrounding media are such dispersive Debye media as the Human Body tissues. The new method is then compared to the simpler Luebbers and Kuntz method that was previously extended to Debye media. The comparison relies on the reflection and transmission of plane waves and on 3-D experiments. It is concluded that the Maloney and Smith method permits a better accuracy to be achieved. It provides accurate reflection and transmission whatever may be the incidence angle of the wave that strikes the sheet.
