Mode Bifurcation and Fold Points of Complex Dispersion Curves for the Metamaterial Goubau Line
P. L. Overfelt, Klaus Halterman, Simin Feng +1
In this paper the complex dispersion curves of the four lowest-order transverse magnetic modes of a dielectric Goubau line () are compared with those of a dispersive meta…
Guided Modes of Elliptical Metamaterial Waveguides
Klaus Halterman, Simin Feng, P. L Overfelt
The propagation of guided electromagnetic waves in open elliptical metamaterial waveguide structures is investigated. The waveguide contains a negative-index media core, where the…
Subwavelength fractional Talbot effect in layered heterostructures of composite metamaterials
Simin Feng, Klaus Halterman, Pamela L. Overfelt
We demonstrate that under certain conditions, fractional Talbot revivals can occur in heterostructures of composite metamaterials, such as multilayer positive and negative index me…
Transparent photonic band in metallodielectric nanostructures
Simin Feng, J. Merle Elson, Pamela L. Overfelt
Under certain conditions, a transparent photonic band can be designed into a one-dimensional metallodielectric nanofilm structure. Unlike conventional pass bands in photonic crysta…
Characteristics of bound modes in coupled dielectric waveguides containing negative index media
Klaus Halterman, J. Merle Elson, P. L. Overfelt
We investigate the characteristics of guided wave modes in planar coupled waveguides. In particular, we calculate the dispersion relations for TM modes in which one or both of the…
