Nanostructured non-magnetic left-handed composites

Materials with simultaneously negative values of effective dielectric permittivity and magnetic permeability have been shown to have negative phase velocity (and refractive index). We propose a new approach to constructing a system with negative refractive index. In contrast to all previous designs, our system is implicitly non-magnetic and homogeneous. The proposed material is based on EM wave propagation inside a strongly anisotropic dielectric material in waveguide geometry. This design is highly scalable from GHz to optical frequencies. We present the theoretical description of the EM properties of the proposed system and several realizations for different spectral ranges.
