Abstract

This paper addresses the influence of the metamaterial losses and dispersion on the performance of double negative non-radiative dielectric waveguides. The lossy dispersive Lorentz model is adopted for both the electric permittivity and the magnetic permeability. The dispersion properties of the longitudinal section magnetic modes and their root dynamics in the complex plane of the longitudinal wavenumber are analyzed. Finally, it is shown that the effect of metamaterial losses may suggest some potential applications.
