The nonlinear left-handed material(LHM) model was analyzed. The expressions of finite-difference time-domain(FDTD) method and perfectly-matched layer in such material were derived. Electromagnetic wave in Kerr nonlinear left-handed material model was simulated. Electromagnetic focus of Kerr nonlinear LHM was observed. Compared to linear LHM, it is observed that the location and the amplitude of the electromagnetic focus in such nonlinear LHM had changed. Various distances from source to LHM slab were concerned. Electric intensity was concentrated at LHM slab edge while the source was far enough.
