    "abstract": "We investigate the characteristics of guided wave modes in planar coupled\nwaveguides. In particular, we calculate the dispersion relations for TM modes\nin which one or both of the guiding layers consists of negative index media\n(NIM)-where the permittivity and permeability are both negative. We find that\nthe Poynting vector within the NIM waveguide axis can change sign and\nmagnitude, a feature that is reflected in the dispersion curves.",
