    "abstract": "On the basis of angular spectrum representation, a formalism describing\nparaxial beams propagating through an isotropic left-handed material (LHM) slab\nis presented. The treatment allows us to introduce the ideas of beam focusing\nand phase compensation by LHM slab. Because of the negative refractive index of\nLHM slab, the inverse Gouy phase shift and the negative Rayleigh length of\nparaxial Gaussian beam are proposed. It is shown that the phase difference\ncaused by the Gouy phase shift in right-handed material (RHM) can be\ncompensated by that caused by the inverse Gouy phase shift in LHM. If certain\nmatching conditions are satisfied, the intensity and phase distributions at\nobject plane can be completely reconstructed at the image plane.",
