摘要：

In this letter, we illustrate how metafilms (the two-dimensional equivalents of metamaterials, also referred to as metasurfaces) can be used to design novel waveguiding structures. Metafilm waveguides can be flexible with low material and radiation losses. They are attractive alternatives to traditional core-cladding types of surface waveguides and, as such, could have potential applications at terahertz frequencies. We show comparisons to full-wave numerical results in order to validate first the proposed waveguiding structure and, second, the technique used in the analysis of the waveguide.
