We address quantum interference of the Zeeman atom embedded in two kinds of structures containing left-handed materials (LHM), which are a single LHM layer mounted on a single mirror (SLSM) and Fabry-Perot cavity filled with a LHM layer by half (FPCLH). Especially, the influence of the dissipation of LHM on quantum interference has been studied in detail. Though dissipation weakens quantum interference in general, it holds nearly complete quantum interference when the thickness of the cavity is small for FPCLH. Moreover, with equivalence of left-and right-rotation polarized dipoles to two spatial orthogonal dipoles, we found the optimum orientation of two orthogonal dipoles which can realize the maximum quantum interference in a certain anisotropic environment. Our research may have potential applications in the designing of microsize devices.
