Abstract

The finite difference time domain (FDTD) method is used to simulate the wave propagation characteristics in lossy left-handed materials (LHM). On one hand, the results show that a focus region can be identified inside the material slab but not as a perfect lens. On the other hand, we can also see that the EM wave decreases during the LHM slab and RCS of the conductive cylinder covered with LHM cloaking decreases in a wind band. Therefore, we have the conclusion that the LHM can be used as stealth materials.
