AMBROSIO, Leonardo André; HERNANDEZ-FIGUEROA, Hugo E  y  TORRES-SILVA, Héctor. GUIDED MODES IN METAMATERIAL SLABS. Ingeniare. Rev. chil. ing. [online]. 2006, vol.14, n.3, pp. 291-298. ISSN 0718-3305.  doi: 10.4067/S0718-33052006000200013.

This paper presents a review of the propagation modes in a slab waveguide consisting of negative refraction index materials, known as metamaterials. Some particular properties of guided modes in a metamaterial slab, such as slow symmetric or antisymmetric slow wave propagation, the absence of fundamental modes for fast waves and the possibility of guided waves in a less dense medium. The analysis is based on field expansions in the guide and the upper and lower spaces of it.
