    "abstract": "A new approach to producing a composite material with negative refraction\nindex is demonstrated. It is shown that a photonic structure consisting of two\ndielectric materials, with positive and negative dielectric permittivities, can\nsupport electromagnetic surface waves which exhibit the unusual electromagnetic\nproperty of left-handedness (or negative refraction index). Depending on the\ndielectric materials, these surface waves localized at the dielectric\ninterfaces can be either surface plasmons, or phonons. The detailed geometry of\nthe structure determines whether this composite left-handed material is\nisotropic, or anisotropic.",
