    "abstract": "We analyze nonlinear properties of microstructured materials with negative\nrefraction, the so-called left-handed metamaterials. We demonstrate that the\nhysteresis-type dependence of the magnetic permeability on the field intensity\nallows changing the material properties from left- to right-handed and back.\nUsing the finite-difference time-domain simulations, we study wave transmission\nthrough the slab of nonlinear left-handed material, and predict existence of\ntemporal solitons in such materials. We demonstrate also that nonlinear\nleft-handed metamaterials can support both TE- and TM-polarized self-trapped\nlocalized beams, spatial electromagnetic solitons. Such solitons appear as\nsingle- and multi-hump beams, being either symmetric or antisymmetric, and they\ncan exist due to the hysteresis-type magnetic nonlinearity and the effective\ndomains of negative magnetic permeability.",
