Abstract: The superlensing effect of left-handed material (LHM) slabs was analyzed using finite-difference time-domain (FDTD) method. The method enabled to explicitly study the dependence of wave behavior on different parameters. The dynamic feature of the imaging process and the dependence of physical parameters on the performance of the superlens were also analyzed. The resolution of superlens was limited by the absorption and the physical dimension of the LHM slabs. The results show that the resolution of image obtained using the LHM slab can overcome the diffraction limit of conventional imaging systems.
