The quantum mechanics system with interaction between quasi-Λ type four-level atoms and multi-mode light fields is discussed. Under the mechanism of quantum interference, the relative dielectric permittivity and the relative magnetic permeability will change remarkably. In certain range of parameters, both of them will be negative. At this time, the left-handedness effect happens.
