摘要：

We studied the surface wave and reflective properties of two types of metamaterials, one that combines a material with dispersive mu with a metal film, and another that possesses arbitrary epsilon and mu. Generic surface wave phase diagrams with respect to epsilon and mu are given. For the first type, we find that the simultaneous appearance of high-impedance reflectivity and a surface-wave gap requires additional mechanisms such as Bragg scattering, while metamaterials of the second type can possess high surface impedance and a surface-wave gap simultaneously.
