Abstract :
Summary form only given. The peculiar characteristics of the mode coupling between standard dielectric waveguides and waveguides formed by a material with negative index of refraction are presented. Some of our theoretical results, describing the anti-directional (antiparallel) nature of such coupling, are shown for the case of the two-parallel-slab geometry.
