Abstract

In this paper, we employ the properties of metamaterials to tailor the modes of metamaterial-dielectric waveguides operating at optical frequencies. We survey the effect of fishnet metamaterial structural parameters such as the magnetic oscillation strength, magnetic resonance frequency and magnetic damping on the double-negative refractive index frequency region in metamaterials and on the hybrid-modes in slab metamaterial-dielectric waveguides. To identify the robustness of the metamaterials to fluctuations in the metamaterial structural parameters, we investigate the behavior of metamaterials under Gaussian errors on their structural parameters. Our survey enables the identification of appropriate metamaterial unit-cell structure and the permissive fluctuations on the structural parameters for further applications of metamaterials in waveguide technologies.
