A new dielectric slab waveguide with double-negative (DNG) film layer and single-negative
(SNG) cover layer is proposed. The dispersion relations of an asymmetric left-handed materials

We calculate the guided band diagram of a metallic film with a one-dimensional periodic arrangement of cut-through subwavelength slits. We find that this system supports two distinct types...
