摘要:

Finite-difference time-domain (FDTD) method is used to simulate the propagation of electromagnetic wave in left-handed material slab (LHMs) with cold plasma model The effects of optical propagation in the left-handed material compared to convex lens are discussed. The wider the LHMs is, the stronger electric field of focusing image in left-handed material slab is confirmed by the simulation with various slab length. However, the outer image point location would slightly moves to the LHMs side when the length of LHMs is reduced.
