文摘
In this work, a slab waveguide consisting of a chiral negative index metamaterial film surrounded by a dielectric medium was considered. The characteristics of both even and odd guided modes are investigated. The field profile, dispersion curves and power distribution for these configurations are also studied. A set of novel features were observed such as negative power in the chiral film and the existence of normalized frequencies less than the cutoff at which waves can propagate.
